Multi-function Indicator - This is a two-color LED that indicates the following:

Red (constant) - Transmitter keyed (PTT switch pressed).

Green (constant) - Busy condition (carrier detected in receive mode).

Option Switches - Each of the six options switches on the front panel (including the one 
located to the left of the display) can be programmed by your system operator to control 
some function. The switch functions can be different for each operating mode 
(conventional, SMARTNET/SmartZone, and Project 25 Trunked). Therefore, up to 18 
functions can be controlled by these switches. Refer to Section 4.1 for more information 
on option switch functions.

ohm, 12-watt external speaker may be used if desired. The internal speaker is disabled 
when an external speaker is used.
