The Samsung Instinct™ is lightweight, easy to use, and reliable, and it offers many features and service options. This list previews some of those features and provides page numbers where you can find out more:
Digital dual-band capability allows you to make and receive calls while on the Sprint National Network and to roam on other 1900 and 800 MHz digital networks where Sprint has implemented roaming agreements (page 55).
Sprint Power Vision provides access to the wireless Internet in digital mode (page 150).
The built-in Bluetooth® technology allows you to connect wirelessly to a number of Bluetooth-enabled devices, such as printers and headsets (page 125).
Email (page 156) and SMS Text Messaging (page 144) provide quick and convenient messaging capabilities.
Games, ringers, screen savers, and other applications can be downloaded to make your device as unique as you are (page 168). Additional charges may apply.
Your Contacts list allows you to store up to 600 entries, with up to seven phone numbers per entry (page 65).
The built-in Calendar offers several personal information management features to help you manage your busy lifestyle (page 77).
The Location feature works in connection with available location-based services (page 45).
Speed dial lets you dial phone numbers with one or two touches (see page 35).
Mobile SyncTM is a service that allows you to back up all of your contacts to the Sprint Web site and then restore them if your device is ever lost, stolen, damaged, or replaced (page 103).
Press
, located at the top of the device. 
Once your device is on, it may display “No Service.” When your device finds a signal and an available network, you are ready to begin making and receiving calls.
If your device is unable to find a signal after 5 seconds of searching, a Power Save feature is automatically activated that searches for a signal periodically without your intervention. When a signal is found, your device automatically returns to the unlock screen. (You can also initiate a search for Sprint service by pressing any key when your device is turned on.)
|
Tip |
The Power Save feature conserves your battery power when you are in an area where there is no signal. |
Press and hold
for two seconds until you see the powering down animation on the display screen.
Your screen remains blank while your device is off (unless the battery is charging).
|
WARNING |
Use only Sprint-approved or Samsung-approved batteries and chargers with your device. The failure to use a Sprint-approved or Samsung-approved battery and charger may increase the risk that your device will overheat, catch fire, or explode, resulting in serious bodily injury, death, or property damage. |
These batteries and accessories can be found at Sprint Stores or through Samsung®; or call 1-866-343-1114 to order. They’re also available at www.sprint.com.
Your device is equipped with a Lithium Ion (Li-Ion) battery. It allows you to recharge your battery before it is fully drained. The battery provides up to 5.75 hours of continuous digital talk time.
When the battery reaches 20% of its capacity, the battery icon (
) blinks. When there are only a few minutes of talk time left, the device sounds an audible alert and then turns off.
|
Note |
Long backlight settings, searching for service, vibrate mode, browser use, and other variables may reduce the battery’s talk and standby times. |
|
Tip |
Watch your device’s battery level indicator and charge the battery before it runs out of power. |
Make sure the power is off so that you don’t lose any stored numbers or messages.
Press down on the end of the battery compartment cover (just below the embossed Samsung logo), slide the cover off (1), and remove the battery from the device (2).
|
WARNING |
Do not handle a damaged or leaking Li-Ion battery as you can be burned. |

Charge your battery as soon as possible so you can begin using your device.
Keeping track of your battery’s charge is important. If your battery level becomes too low, your device automatically turns off, and you will lose any information you were just working on. For a quick check of your battery level, glance at the battery charge indicator located in the upper-right corner of your device’s display screen. If the battery charge is getting too low, the battery icon (
) blinks and the device sounds a warning tone.
Always use a Sprint-approved or Samsung-approved desktop charger, travel charger, or vehicle power adapter to charge your battery.
Plug the flat end of the charger into the device’s Accessories/Power Cable Jack and the other end into an electrical outlet.

With the Sprint-approved Li-Ion battery, you can recharge the battery before it becomes completely run down.
There is no longer a need to use a navigation wheel or dial pad button. The Samsung Instinct™ is a
touch-sensitive device which allows you to not only select an onscreen option with a single touch, but also scroll through long menu lists by simply sliding up and down through the display with either a stylus or by using your fingertip.
Accessing Menus
When the device is locked and
is pressed, the Instinct displays the unlock screen.
To access the device’s Phone Functions and Main Functions menus, you must first press and hold
to unlock the device (as described at the top of the unlock screen).
The Phone Functions menu is the first one displayed.
To access a menu:
Press
to access the Phone Functions menu.
– or –
Press
to access the Main Functions menu.

As you navigate through the menu, menu options are presented onscreen as scrollable lists that allow up or down navigation.
|
Note |
The One Hand Operation of the menus is set to Right Handed by default. See “Changing the One Hand Operation Setting” on page 23 to change to Left Handed. |
To navigate through a scrollable menu:
Touch a desired onscreen menu tab (located at the bottom of the screen).

Touch and gently press an onscreen option.
From the available list of options you can either:
Touch and gently press an entry to activate it.
Firmly press and slide your finger up or down the screen to scroll through lists of menu items. Scrolling on your Instinct requires that your press more firmly on the screen than the gentle press required to open menu items.
The image below shows how to access the Display menu (
> Main > Settings).

For a diagram of your device’s menu, please see “Your Device’s Menu” on page ii.
|
Tip |
When scrolling through a list (see illustration on the right above) make sure NOT to tap or press individual entries on the list. This action will open the list entry. |

|
Tip |
The screen on your device is touch-resistive, which means that when you touch an item to select it or when you drag your finger to scroll, you have to press down slightly to activate the item. This helps avoid selecting menus or items unintentionally. You can adjust the touch sensitivity of your screen through the Settings menu. See “Touch Settings” on page 44. The smaller the contact point on your screen, the less pressure required. In this case, touch the screen with the tip of your finger, your fingernail, or the stylus. |
As you navigate through the menu, menu options are highlighted. Select any option by pressing it on screen with either your fingertip or a stylus.
For example, to view your text messages:
Press
and touch Main (
) > Messaging. (If you have any text messages, they are displayed.)
This drop-down screen provides some quick device reference information such as: Date, Signal Strength, Ringer Status, Battery Charge Status, Power Vision status, as well as new messages and emails.
Touch the top line of the LCD screen.

Touch the popup screen once to close it or wait a few seconds for it to automatically hide.
The Instinct allows you to configure the Power Search tab to be on either the right or left of the screen.
As an example, when the Right Handed option is selected, the Power Search tab is located along the right side of the screen and Contacts entries are then selected by pressing their name fields along the left side of the LCD.

Press
and touch Main (
) > Settings > General > One Hand Operation.
Touch either Right Handed (to place the Power Search tab along the right of the LCD) or Left Handed (to place the Power Search tab along the left of the LCD).
There are several pages where you’ll be asked to make a field selection and then enter a value by either touching the up/down selection arrows or quickly sliding through these values by using either your fingertip or a stylus. One such example can be found within the Alarm page.
Press
and touch Main (
) > Clock > Alarm >
.
Touch the Time field and then adjust the hour and minutes values by using either the up/down input arrows or by quickly sliding over the numbers.

The Instinct allows you to detach an entry from a list and then either move its location (within that same list) or drag it into the Trash Bin for deletion.
From a screen containing entries, touch and hold an entry. You will notice that it turns a lighter blue as it detaches from the list.
While still holding the entry, wait until it appears to detach from the current list and an outline forms over its current location.
Place it in a new location (as with a Speed Dial entry) by hovering it between two existing entries and then releasing it.
– or –
Delete it by dragging the entry over the Trash Bin (
) and then releasing it. The entry then disappears into the icon.
