5.5. MANUAL SETTINGS

Normally, settings are carried out by a VT100 terminal or PC. Additionally, if

manual settings are unavoidable, rotary switches on the motherboard enables

the operator to optimize the gain and to set the channels.

To enable the manual setting of attenuation and channels, ensure that the DIP-switch

1 of the mode switch [1] is in position ON (manual mode). An attenuation of 30 dB

max. in steps of 2 dB can be set in the UL- and DL path for channel and band

selective repeaters. The channel settings are only available for channel selective

repeaters.

∗ Note: While DIP-switch 1 of mode switch (1) is in position ON (manual

mode), software settings via VT100 terminal are not possible!

Quering the status can still be carried out.

Example: Position 0 of the rotary switches S7/S8 equals 0 dB attenuation. Position 1

attenuates the signal by 2 dB, position 8 for instance attenuates by 16 dB. To

achieve max. attenuation (30dB), turn the rotary switch of the corresponding path to

position F.
