Ensure all other stations are not transmitting on the intercom or have an open MIC. If no
headset is connected to a crew station, no action is required.
Ensure that the station is receiving no long-range radio audio.
Power up the wired system and the TAP.
On the TAP, press and hold the Channel SET and LED pushbuttons at the same time for five
seconds.
Power up a TPT and test for echo by speaking to the wired ICS.
If echo is heard, reduce the station’s volume control slightly until the echo is eliminated.
3.4.3
ORDER SYNCHRONIZE ACCESS POINT Setting (Change TAP Channels)
When a TAP is in the network, it is always the MASTER. Changing the channel of the MASTER
unit of the network will disconnect all logged on operators. All operators will have to change to the
new channel for their unit to be re-connected to the original network.
This setting allows a TPT unit the ability to change the channel of a TAP.
Notify all operators on the network that the channel is about to be changed.
Set the SLAVE unit to the channel desired for the TAP.
Press and release the
M
button until the SynVoice announces the “ORDER SYNCHRONIZE
ACCESS POINT” setting.
Press and release the * button on the TPT. The user will hear SynVoice announce “ORDER
SYNCHRONIZE ACCESS POINT”.
Press and hold the “SET CHANNEL” button on the TAP.
Press and release the
PTT
button on the TPT.
The SLAVE unit will initiate a re-logon to the new network channel of the MASTER. The
successful logon is confirmed to the operator via the SynVoice message “LOGON OK”, and
communication can then continue between operators on this channel.
For operation with groups of vehicles in close proximity, the TAP channels in groups of ten
should be avoided (for example: CH 1, CH11 and CH 21)
3.4.4
ORDER CHANGE MASTER Setting
The ORDER CHANGE MASTER setting
should not be used when a TAP is operating as
the MASTER in a network. It may be used
when a TPT is used as a MASTER.
CAUTION
