useful if the interconnected call is put
on hold, particularly “music on hold”. When the mobile gains control, Vox
mode is disabled until the mobile releases PTT.
0 = Half Duplex
1 = Simplex, Sampling
2 = Simplex, Smart Sampling
Example : To program Simplex Smart Sampling enter the following sequence: 50# 2#
Sample Rate for Sample Mode and for VOX active (51#)
When in Simplex Enhanced Mode the 4700VP detects the presence of audio and automatically switches to enhanced
mode, decreasing sampling to the pre-programmed rate. This rate is user programmable from 1 second ~ 30 seconds
in ten steps.
0 = 1 sec
1 = 2 sec
2 = 4 sec
3 = 5 sec
4 = 8 sec
5 = 10 sec
6 = 15 sec
7 = 20 sec
8 = 25 sec
9 = 30 sec
Example: To change the enhanced sampling rate to 5 seconds enter the following sequence: 51# 3#
Sample Rate for VOX Inactive (52#)
The sample rate for
Vox Inactive
code controls the normal sampling rate (no audio present on the phone line). This
feature is user programmable from 500ms ~ 15 s.
0 = 500 ms
1 = 1 sec
2 = 1.5 sec
3 = 2 sec
4 = 3 sec
5 = 4 sec
6 = 5 sec
7 = 7 sec
8 = 10 sec
9 = 15 sec
Example: To program the model 4700VP for 1 second interval, enter the following: 52# 1#
Maximum Vox Timer (53#)
This timer controls the length of time which the 4700VP will keep the transmitter continuously keyed. Then the unit
will switch to sample mode allowing the mobile operator to take control of the unit. This feature is very useful if the
interconnected call is put on hold particularly on “music on hold”. Factory default is 12 seconds and is user
programmable up to 25 seconds or turned of.
0 = off
1 = 3 sec
2 = 4 sec
3 = 6 sec
4 = 8 sec
5 = 10 sec
6 = 12 sec
7 = 15 sec
8 = 20 sec
9 = 30 sec
Example: To program the maximum Vox timer to 3 seconds enter the following sequence: 53# 1#
Vox Hang Time (54#)
Vox Hang Time is the amount of time which the interconnect stays on the air after the telephone line audio was last
detected. The 4700VP is shipped from the factory with 1 second Vox hang time. This means that the Vox hang time
will keep the transmitter keyed for at least one second after the telephone audio ceased.
0 = 200 ms
1 = 500 ms
2 = 1 sec
3 = 1.5 sec
4 = 2 sec
5 = 3 sec
6 = 4 sec
7 = 5 sec
8 = 7 sec
9 = 10 sec
Example: To program this timer for 1.5 seconds enter the following sequence: 54# 3#
Sampling Window Setup (55#)
The sampling window duration is the period of time required for the 4700VP to switch the base station radio from
transmit to receive to determine whether a mobile is transmitting or not. while observing COR. The sampling
window period can be easily adjusted by pressing digits 0 ~ 9 while observing COR. When the proper window
timing is set, the COR LED will flash when the 4700VP samples. Pressing the pound key (#) will accept the code
and exit the sampling window setup mode. Star key (*) will abort the last digit entered. 95 ms is the factory default
but it is not necessarily the appropriate setting for your transceiver. Performing this procedure is essential for proper
operation.
0 = 50 ms
1 = 80 ms
2 = 95 ms
3 = 115 ms
4 = 125 ms
5 = 135 ms
6 = 150 ms
