You may not reconstruct, self-repair, or disassemble the Wireless Doorbell. This can damage the transmitter and/or the
receivers.
●
Maintenance, modifications, and repairs may only be carried out by an expert or a qualified shop.
●
Check the devices from time to time for damage. Never use a device if it shows signs of damage.
●
Make sure your mains socket supplies the correct power voltage to avoid damage to the receivers.
●
The mains socket for the receivers must be easily accessible.
●
Unplug the receivers from the mains socket if you do not use the devices for an extended period, and before cleaning.
●
Never force the mains plug of the receivers into a mains socket; if it does not fit easily into the mains socket, please stop
using it. Always make sure that the mains plug of the receiver is properly connected to the mains socket.
●
If the power fails during the operation, pull the receiver immediately from the mains socket.
●
If there’s a smoke, fire, or a strange odor coming from your receiver, you should turn off the circuit breaker or fuse box’s
main switch and remove the receiver from the mains socket.
●
For safety reasons, always unplug the receivers in case of a thunderstorm.
●
Do not cover a receiver while it is in operation as this may cause the it to overheat. This poses a risk of fire, electric shock,
or injury.
●
Keep the devices away from heat and in or close to areas where the surrounding temperature is relatively hot (e.g. stoves
or other sources of heat). Never use the devices near naked flames.
●
The devices are designed to work best in normal ambient temperatures between 0° and 35°C and to be stored at
temperatures between -20° and 50°C. The devices may be damaged and the battery life of the transmitter may be
shortened if the devices are stored or used outside this temperature range. Do not subject your devices to dramatic
changes in temperature. Do not store your devices in direct sunlight for extended periods.
●
Do not use the devices in a tropical climate.
