9.1 General

The system normally operates without any operator intervention or maintenance. If in the

unlikely event of any unit failure, the faulty repeater should be replaced. A failed unit can be

removed and replaced with a spare while the rest of the system (other repeaters) is still

operating. However, the power supply of the failed repeater should be isolated from the

power before anything is replaced.

In the event of a malfunction in the system, the status of the antenna systems as well as the

continuity of the cabling should be checked before replacing any modules within the

repeater.

9.2 Preventative Maintenance

The repeater does not require preventative maintenance apart from changing the battery

once every three years.

9.3 Component Replacement

Except for the backup battery, none of the modules in the repeater can be replaced without

removing the repeater from its mounting and opening the cover of the repeater.

9.4 Product Disposal

Disposal of this product must be handled according to all national laws and regulations. For

detailed information regarding materials, please refer to Axell Wireless.
