1.7 Pre-Installation Test for Wireless Clocks
It is recommended to test the VS4500 and the entire system prior to installation in order to verify proper operation and get
familiar with the unit operation.
Follow these steps to perform a pre-installation test:
1. If your system is equipped with an internal transmitter, connect the BNC antenna cable to the RF-OUT terminal at the
back of the VS4500.
If your system uses an external transmitter, connect the transmitter data cable between the VS101-XX transmitter and
the DATA I/O port at the back of the VS4500. Connect the antenna to the external transmitter’s RF-OUT terminal.
2. Connect the provided power supply to the POWER jack at the back of the VS4500 and turn the power switch to ON
position. The main menu should appear with the PAGE TO: displayed on the top line.
If you are using an external transmitter, make sure it is powered on.
