function previously described then transmits the pre-
programmed 5-tone code.
Manual 5-Tone Codes
NOTE: This requires the optional 5-tone unit.
Your transceiver may be programmed to allow
5-tone codes to be sent manually:
1. To activate this function, press the switch pro-
grammed for the transmit code function. Then enter
the desired transmit code (up to seven digits) using
the number keypad.
2. Activate the call function to transmit the 5-tone
code. Blinking indicates that the keypad entry is
acceptable.
2.5 PROGRAMMABLE FUNCTIONS
2.5.1 GENERAL
The functions described in this section are avail-
able only if they have been programmed. When appli-
cable, they are controlled by the programmable
switches described in Section 2.2. Therefore, the spe-
cific use of each switch varies. The table below can be
filled out and used as a reference to identify the func-
tions that are controlled by these switches.
NOTE: Programming determines the availability of
the following functions. Therefore, a function is avail-
able only if it has been programmed. Refer to
Table 3-2 for more information on these switches.
2.5.2 KEYPAD LOCK
This function disables all keypad keys except the
one used to control this feature. This prevents keys
from being accidentally pressed. Some channels may
be programmed so that this feature is not available. To
toggle this function, press for 1 second the switch pro-
grammed for the Keypad Lock function. The keypad
is locked when the key icon (
) is displayed.
2.5.3 PRIORITY CHANNEL
This function is used to quickly select a prepro-
grammed priority channel. When the switch pro-
grammed for this function is pressed, “PRIO” is
briefly displayed and the priority channel is automati-
cally selected.
2.5.4 SCAN
The scan feature monitors a preprogrammed
group of channels. When a signal is detected that the
transceiver is programmed to receive, scanning stops
and the message is received. Shortly after the mes-
sage is complete, scanning resumes. To turn scanning
on and off, press the switch programmed for Scan. A
message may be displayed while scanning.
“Lockout Scan” (preprogrammed list scan) or
“Priority Scan” can be preprogrammed. When the
“Power-Save” function is activated, the transceiver
checks all preprogrammed channels and then returns
to the power save mode.
2.5.5 KEY BEEP
The function provides a confirmation tone when
keys are pressed. To turn this feature on and off, press
the switch programmed for the Beep function for
1 second or longer.
2.5.6 MONITOR
The Monitor function allows the transceiver to be
manually unsquelched to determine if a channel is
busy. Channels may be programmed so that either all
messages or only those messages intended for you are
received. Therefore, if you hear only your messages,
the channel must be monitored before transmitting to
make sure someone else is not using it. If you were to
transmit while someone else is talking, you would
probably disrupt their conversation.
To enable monitoring, press the switch pro-
grammed for the Monitor function. If the channel is
