Synchronization System Setup (ctd.)
Positioning Transceivers:
The main transceiver should be installed in a central location where there is a minimum number of
walls between the transmitter and clocks. After the main transceiver has been installed, begin installing
the secondary clocks nearest to the main transceiver, followed by whichever clocks are nearest to the
secondary clocks, and so on. Each secondary clock within range of the transceiver should receive data and
begin correcting itself within five minutes of being powered on. Be aware of walls or other obstructions
made of thick concrete or sheet metal, as these may block the signal entirely.
Manually setting a connection between two or more Valcom Wireless clocks:
1. Identify two clocks. The one which is receiving a signal from the Master Clock is your Transmitter
clock, the one which is not receiving a signal is your Receiver clock.
2. Press the Transmit/Receive button on the Transmitter clock once. The second hand will move to the 40
second position and the clock will stop running. The Transmitter clock is now in transmission mode.
3. Press the Transmit/Receive button on the Receiver clock twice. The second hand will move to the
20 second position until the Receiver clock receives time from the Transmitter clock. You may
perform this step with more than one Receiver clock at the same time.
4. As you move further away from the main transceiver, use one of your now-synchronized Receiver
clocks as your new Transmitter, and continue the process.
System Setup Options
There are three ways to operate a system of Valcom’s Wireless clocks. The user may choose one or a
combination of the options listed below:
1. No clocks are used for transmission. This option should only be taken if the user already has a main
high-powered transceiver and as many repeaters as needed to cover the premises.
2. Battery powered clocks are used as transceivers/repeaters. This option assumes that there is at least
one high powered transceiver in range of enough of the clocks that the clocks can repeat the signal
to all other clocks in the system.
3. Locally powered clocks are used as transceivers/repeaters. This option assumes that there is at least
one high powered transceiver in range of enough of the clocks that the clocks can repeat the signal
to all other clocks in the system.
Before performing any of these options, the user must install and power the master clock and main
transceiver first.
