Changing the Frequency
It is easy to change the frequency of the Series 310 simply by replacing corresponding
frequency crystals in both the Transmitter and the Receiver.
Note: To replace a new crystal, please note that there are two kinds of
frequencies (VHF and UHF) available. The indication of VHF or UHF is
shown on the PC board with a check mark “V”. Please make sure not to
replace a VHF crystal unit into a UHF PC board, or vice versa.
Instructions:
1. Pry up the crystal with a flathead screwdriver.
2. Remove the crystal from the system.
3. Use needle nose pliers to straighten both pins of the new crystal.
4. Insert the new crystal vertically into the PC board.
5. Press the new crystal down into the socket.
Attention: The Transmitter frequency will be different from the Receiver
frequency. For example, the transmitter crystal are labeled
T01 thru T40 and receiver crystals are labeled R01 thru R40.
