Power on/Volume/Power off
Turn the radio on by rotating the off/on/volume control clockwise.
You will hear a click and (if enabled via dealer programming), the radio’s self-test alert
tones. Increase the radio volume by continuing the clockwise rotation.
To turn the radio off, rotate the control anti-clockwise until a click is heard.
Your SM2102 radio has a sophisticated microprocessor control, which provides a range
of audible alert tones. Upon each power-up, a quick melody indicates that the self-test of
the microprocessor functions has been completed. A sequence of audible tones may be
sounded with any of the following conditions:
• Attempt to transmit on a channel set for receive only
• Attempt to transmit on a channel that is already in use when busy channel lockout has
been programmed into the radio.
• Transmitting time has exceeded time-out timer programmed length.
• Selecting a channel with no programmed frequency.
• TX inhibit is in operation.
• Low battery condition
