Option Buttons 1, 2, and 3 - Each of these buttons can be programmed to control a 
specific function (see Section 4.2, "Option Keys / Buttons"). In addition, they can be 
programmed for soft power down (see Section 3.1.3, "Standard and Soft Power Down"). 
These buttons can also be temporarily disabled by the keypad lock feature (see Section 
3.6, "Keypad Lock") or permanently disabled.

bottom of the battery outward.

Accessory Connector- This is the connection point for optional accessories such as a

programming the radio or for data equipment when the P25 Packet Data feature is used 
(see Section 5.13.14, "P25 Packet Data"). Details of operations through the connector 
(such as external microphone signal routing, etc.) are determined by programming.

can be programmed:

• Time/Date
