There are four (4) ways to install Valcom’s Analog Wireless Clock system. The user can choose
any of the combinations listed below, or any combination of the three (3).
Option #1:
There is a main high powered transceiver in the building (V-WMCA) and repeaters (V-
WMCRA) as needed to cover the entire premise. In this option, the system does not depend
on the slave clocks for transmission.
Option #2:
There is at least one (1) high powered transceiver (V-WMCA) in the building and in order to
cover the entire premise, the
battery
-operated clocks are used as transceivers/repeaters.
Option #3:
There is at least one (1) high powered transceiver (V-WMCA) in the building and in order to
cover the entire premise, the
power (24V or 110V)
operated clocks are used as transceiv-
ers/repeaters.
Option #4:
There are multiple transmitters that will cover the entire building or campus.

IMPORTANT: We highly recommend installing the main transceiver (V-WMCA) before the
installation of the Valcom Wireless analog clocks.
In order to install the clock, simply remove the battery cover, and install two (2) D cell batteries
(recommended battery type: Duracell
®
PROCELL
®
). After installation of the batteries, replace the
battery cover and the clock should start correcting within five (5) minutes.
Normal Mode/Economy Mode
The Valcom Wireless Analog Series clocks have two (2) different modes in which they will operate.
Normal mode allows the clock to transmit/receive every two (2) hours. This mode will allow the
clock to have a 5 year battery life (provided good reception). Economical mode allows the clock to
transmit/receive every four (4) hours. This mode will allow the clock to have a 8 year battery life
(provided good reception).
Normal mode is defaulted when shipped from the factory.
To toggle this mode, push and release the Diagnostic Switch and the Transmit/Receive switch si-
multaneously. If 5 year mode is selected, the LED will be solid RED for one minute and the second
hand will go to 5 (25 seconds). If 8 year mode is selected, the LED will be solid GREEN for one
minute and the second hand will go to 8 (40 seconds).
IMPORTANT: If a clock is being added to an existing system (existing clocks date coded
prior to December 2009), it must be in normal mode.
