Radio On/Off and Power-Up

1.Turn the radio on by rotating the volume control clockwise. The radio goes through a power-up self check and, if it passes the check, the display momentarily shows “SELF TEST.”

If the radio fails the self check, the display shows “ERROR XX/XX” (where XX/XX is alphanumeric), accompanied by a low-pitched tone. Turn the radio off, check the battery, and turn the radio back on. If the radio still does not pass the self check, a problem exists in the radio. Contact your nearest Motorola Service Shop.

Note: The power-up self check verifies that the radio’s microprocessor-based systems are working, but it does not check all of the rf components, nor does it check the operation of all customer -specific features. Motorola recommends that the functionality of the radio be periodically checked by an authorized Motorola service shop.

2.Turn the radio off by rotating the volume control fully counterclockwise until you hear a click.

Selecting a Trunked System and Mode

Before you can send or receive on a trunked system, the radio must be set to the desired system and mode; in trunked operation, a mode is a trunked talkgroup and all features “slaved” to it. Your radio can support up to 15 different trunked systems, selected by mode selector knob positions 1 through

15.Each system can have up to 10 different modes associated with it. To select a system and mode:

1.Turn the radio on and set the mode selector knob to the desired system position (1 through 15).

2.Press the right arrow key ( ) until “SUB” appears on the display.
