Used together with a call transmitter (call button), the hand pager (signal receiver) ZJ-41H has been developed to receive instant messaging and to improve communication processes.
The wrist watch receiver ZJ-41H is wireless and works via radio frequency. It has an integrated rechargeable battery, so it only needs to be plugged in to be charged.
The call display is made in a simple way: the led is on when a call transmitter is triggered (the led corresponding to the channel in which the transmitter was paired). The ZJ-41H has 4 channels (leds) and can be paired with up to 5 transmitters on each channel.
