8 Maintenance
8.1 General
F
Note:
The Repeater does not require preventative maintenance measures.
It is only recommended to replace the RAM/RTC battery after three years usage as a
prophylactic measure. The nominal lifetime of these batteries is five years under normal
environmental conditions.
In the event of a malfunction it is advantageous to check the status of the antenna systems as
well as the continuity of the entire cabling including connectors, before replacing the
modules.
Maintenance on the Repeater shall be performed only by replacing modules. Soldering on
printed circuit boards shall be avoided. In order to sustain warranty take care not to damage
unintentionally the seals on the modules.
The spare part list, consequently, contains only units, which can be replaced without tuning or
complex soldering work.
F
Note:
Defect parts should be replaced by original parts from MIKOM only.
All interventions inside the housing are at one’s own risk.
During maintenance ensure that the Repeater has been disconnected from
mains.
Open the lock at the connector panel and remove the cover plate. To open the housing use a
Torx key and unscrew the four Torx screws.
8.2 Replacement of the fuses (mains)
The mains cable is protected with two fuses F1 and F2 8A type MT. They are accessible
inside of the Repeater at the fuse terminal on the right side. Open the screw plug for the fuse
and take out the fuse.
F
Note:
Use only fuses of the same type and the same rating when replacing!
See figure 5-5 Screw terminal for position of the 8A fuses.
