TP-4800 Series Operation
NOTE: Fully charge your battery prior to operation.
TrunkedandConventionalMode
Your Maxon TP-4800 Series may be programmed to operate
with both Trunked and Conventional modes. Each System can
beindividuallyprogrammedtooperateineithertheTrunked
or Conventional Systems. There are only a few differences in
their operation and these are detailed as follows.
ChannelMonitoring
WhileonaTrunked System, channelmonitoring isperformed
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 button is pressed, the
red TX indicator flashes momentarily to allow the transceiver
and System to connect properly. When the red TX indicator
glowssteadily,voicetransmissionmaybegin. IfyourMaxon
Dealer has enabled the "Clear to Talk" tone option, the radio
willemitashorttonesignallingvoicetransmissionmayoccur.
InConventional Systems,there is no System "handshaking"
and voice transmission may start immediately.

desired volume level. (Pressing any of the function
keys will provide a "key press" tone. Use this tone
to set desired audio level).
C. Press the "SYStem" and "GRouP" keys until the desired
System and Group are displayed.
D. If a Conventional System is selected, the channel must be
monitored before transmitting. Press and hold the M
Monitorbutton.Thisdisablesallsquelchsystems
and allows you to hear any transmissions on this
channel.
E. Press and hold the P-T-T button on the side of the
