SP-150 Operation
Your Maxon SP-150 can be programmed to operate in
both Trunked and Conventional modes. Each System can
be individually programmed to operate in either Trunked
or Conventional Systems. There are only a few differences
in their operation and these are detailed as follows:
Channel Monitoring
While on a Trunked System, channel monitoring is performed
automatically by the radio transceiver. In accordance with
the FCC Rules, while operating on a Conventional System,
the channel must be monitored prior to transmitting. In both
Trunked and Conventional Systems, operation may vary from
System to System. Your Maxon Dealer will be able to assist
with particular operational parameters and procedures for the
various Systems and functions.
System "Handshaking"
In a Trunked System, when the P-T-T is pressed, the red TX
indicator flashes momentarily to allow the transceiver and
System to connect properly. When the red TX indicator glows
steady, voice transmission may begin. If your Maxon Dealer
has enabled the "Clear-to-Talk" tone option, the radio will
emit a short tone signaling voice transmission may occur. In
Conventional Systems, there is no System "handshaking" and
voice transmission may start immediately upon pressing the
P-T-T.
Busy System Queuing (Dealer Programmable Option)
If enabled by your Dealer, busy System queuing will monitor
the System for activity. Once the System becomes available,
the System will automatically be accessed and held for a
period of time (determined by your Dealer), allowing you to
transmit on the System. A tone will sound and a flashing
