PROGRAMMING

November 1998
Part No. 001-7600-001
Parameter Description
Emer Sw
On Timer
Sets the period in seconds that the Emergency function key must be pressed to activate the emergency function.
An emergency call is initiated by pressing the Emergency key for longer than this time.
Emer Sw
Off Timer
Sets the period in seconds that the Emergency function switch must be pressed to cancel an emergency call.
This must be done before the call is transmitted because once it is transmitted, it cannot be canceled.
Emer
Start/Repeat
Programs the delay and interval period in seconds for emergency calls. When the emergency switch is pressed
and held, the emergency call is transmitted after this delay period. If the Emergency Repeat function key is pro-
grammed (see Table 4-2), the transceiver then transmits repeatedly at this interval until an “Emergency Cancel”
code is received.
Rx EXO Sets the condition of the horn output (pin 6) of the optional accessory cable in the receive mode. OFF = Horn
drive control out, ON = Send (to ground when signal is received). One use of the “ON” condition may be for
some type of simplified repeater system.
Rx EXO
PTT
When Rx EXO is programmed “On”, pin 6 of the optional accessory cable is grounded for this period when
receiving a signal. Normally this parameter is set to “0”.
EXPTT
Delay Timer
Sets the period that the transmitter stays on after the receive signal disappears.
Tone Mute
EXPTT
Enables or disables the CTCSS/DTCS (Call Guard) function with an external PTT signal. “On” disables and
“Off” enables CTCSS/DTCS.
Low Beep
Frequency
Sets the low beep tone frequency for 400 - 2998 Hz. The nearest available frequency is automatically selected.
High Beep
Frequency
Sets the high beep tone frequency for 400 - 2998 Hz. The nearest available frequency is automatically selected.
Character
Editor
Special characters can be designed using this function by enabling the available 14 segments in any combina-
tion desired. The special characters created then can be entered when programming the “Text” parameters in the
various screens. Up to 16 characters can be programmed and stored in locations A-P. To enter a special charac-
ter when programming text, press the PgUp or PgDn keys to scroll through and select the desired character.
Special characters can be displayed in positions 3-7 (1 and 2 must be standard characters).

4.5 UNIQUE PMR (EUROPEAN) SCREENS
4.5.1 GENERAL
Selecting LMR or PMR in the Model menu (see
Section 4.4.6) affects what parameters are displayed in
some screens and also what additional screens are dis-
played. Basically, selecting the LMR (U.S.A.) model
displays parameters for the 2-tone option, and select-
ing PMR (European) displays parameters for the
5-tone option.
NOTE: Optional 2/5-Tone Kit, Part No. 585-7500-
026, is required to have the 5-tone function.
