Status Indicators and Audible Alert Tones
Your SP-510 has a sophisticated microprocessor control which provides a
series of audible alert tones.
Upon initial power up, a quick melody indicates that the self-test of
the microprocessor functions has been completed satisfactorily.
A series of 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 *
· Low battery condition
·
Selecting a channel with no programmed frequency
Indicates a function that is initially programmed into the radio by your
Maxon Dealer.
NOTE: All audible tones can be programmed off for silent operation.
