The used batteries must not be discarded, but should be disposed of in
accordance with the existing rules for environment protection.
The repeater should be installed indoors, in spaces with normal air humidity. When selecting
the location of installation, remember that thick walls, metal partitions, etc. reduce the range
of the radio signal. The electrical circuit to which the repeater is to be connected must have
suitable protection.
1. Open the repeater enclosure.
2. Place the repeater at the location of future installation.
3. Make an opening for the power wires in the enclosure base.
4. Temporarily connect the repeater to 230 VAC mains.
5. Replace the cover.
6. Register the repeater in the system (see: PERFECTA / VERSA control panel installer
manual, MTX-300 controller manual or MICRA module manual).
You do not have to register the repeater in the system but its operation will not be
supervised if unregistered (power failures, lack of presence or tamper will not be
reported).
