CAUTION
1. When the receiver is on and LCD screen displays “UN LOC”, or when the
transmitter is on and its red light ashes continously, it means that the
receiver or the transmitter malfunctions, please contact CAH for service.
2. If you are using several sets of this system simultaneously, please select
the operating frequency (or channel) carefully to prevent any signal
interference.
3. Receiver
’ s operating power voltage is 220V (±10%); power voltage outside
this range may cause malfunction to the receiver.
4. Battery must be inserted into the battery compartment of the transmitter
at the right polarity. Wrong polarity may cause damage. (Damage caused
by such negligence will void your warranty.)
5. The sensitivity value of the receiver should not be lower than 15dB;
otherwise, the signal will be weakened due to the increase of signal noise
ratio at a distant point.
注意事项
1. 当接收机开机后显示“UN LOC”，或发射器开机后红灯持续闪动
时，表示接收机或发射器出现故障，请发回厂家检修。
2. 若需要同时使用多套本系统时，请仔细选择工作频率（或讯道），以
免干扰。
3. 接收机外接电源的工作输入电源220伏（±10%），若过低或过高可能
会影响本机的工作状态。
4. 发射器在装入电池时，切勿将电池极性装反，否则可能损坏本机。
5. 使用接收灵敏度选择功能时，所选择的数值最小应在15分贝，否则在
距离较远时信噪比会恶化。
