Keypad Lock
The i80s phone includes a Keypad Lock feature that enables you to quickly lock 
the phone’s keypad to avoid inadvertently pressing keys or placing calls. Once 
Keypad Lock is activated, you can only perform the following tasks:
turn your phone on and off
unlock the keypad
receive incoming calls, messages, and alerts
NOTE: Emergency calls cannot be placed while Keypad Lock is 
activated. 
Before locking your phone’s keypad, you may want to read this entire section to 
learn how to respond to incoming calls, messages, and alerts.

With phone powered off, remove the battery. See “Detaching the 
Battery” on page 9.

With the back of the phone exposed and the 
antenna pointing up, locate the SIM cover and 
gently push it to the right. Lift the cover up.

Very carefully lift the SIM out of its holder. Do not touch the gold-
colored areas of the SIM card. 
NOTE: Protect the SIM card as you would any delicate object. When 
the SIM card is not in the phone, you should store it in 
something protective, such as a mailing envelope.
