Note: A low-level hum or buzz in the received audio MAY be
experienced when the TPL code OZ (254.1 Hz) is used. This PL
code is at the high end of the sub-audible frequency range and
may be heard in the audio under certain circumstances. Use of
this code should be avoided if possible.
Note: Refer to the screens provided beginning on page 148.
These figures show examples of the various possibilities
available for Transmit PL and Receive Squelch.
Power Level Power level changes are not allowed in 800 MHz models. Use the UP/
DOWN arrow keys to make your selection. The power level is a low/
high power setting based on codeplug information contained in the
radio. Choose High power for extended range and Low power for
extended battery.
The default is High.
Repeater Access Use the UP/DOWN arrow keys to enable/disable this feature. This
feature allows you to selectively activate repeaters either manually or
automatically with MDC signalling. Up to eight repeater access codes
can be programmed for each radio.
The default is Disabled.
RAT Code The RAT code is varied in accordance with the Repeater that is
applicable for this channel. Each Repeater Access Table (RAT) code is a
two-byte unit ID of the repeaters you may choose from.
The default is Code 1.
Keypad Programming This field will be visible only for JT1000 radios. This field will NOT be
visible for HT 1000 or VISAR radios. Note that there is also a radio-wide
User Programming Enable/Disable field on the JT1000 OPTIONS screen
(F4/F3/F2/F3).
Use the UP/DOWN arrow keys to enable/disable this feature. Enabling
this field allows operators to program frequency, PL code, bandwidth,
and power (including MSPL) on the selected channel. When this field
is disabled, the operator will be prevented from programming these
variables on the selected channel.
The default is Enabled.
