TRANSMITTER LOCKING
- Press the SET button and hold it down until the LCD shows "LOCK".
- The display will show either "LOC ON" or "LOC OFF".
(LOCK ON means that the system is locked at a frequency. Frequency setting cannot be changed, and the
system cannot be turned off).
- Use the Up & Down buttons to select either LOC ON or LOC OFF.
- Press the Set button again to confirm your selection
WARNING
1. If the receiver is turned on, showing cc Un LOCK" on the display, or the red LED indicator on the trans-
mitter is blinking, it means that the receiver or transmitter is out of operation. In that case, refer to your
dealer.
2. If you use more UHF systems at the same time, set the frequency of each system as far from the
other frequencies as possible to avoid interferences between the systems.
3. When inserting batteries into the transmitter (handheld type or belt case), ensure their proper polari-
ties; otherwise, it may result in damage to your transmitter.
4. Set a proper sensitivity of the receiver to obtain the best possible reception.
