to the environment. Primarily, recycle all waste materials that can be

recycled and sort waste so that it can be disposed of according to local

regulations.

RBS 2308 and RBS 2309 User’s Guide In this example, Far End and RBS refer to the figure above. Maximum input signal level at the Far End is -15 dB. The cable attenuation is not known. 1. Set LBO A to “Long h. ALBO, -15 dB”. The cable attenuation is measured by the RBS to 5 dB. 2. The value of LBO A is set automatically by the RBS. 3. Set LBO B, C and D (not connected) to “Short h., 0 - 133 feet”.

RBS 2308 and RBS 2309 User’s Guide Note: Using the OMT, always reload the software and install the appropriate IDB after moving a used flash card to another cabinet. This ensures consistent software and correct configuration. Note: The RBS must be in Local mode in order to accept a new or modified IDB. Note: Do not touch the RBS when any indicators are double-flashing. See section Double-Flash Indication of Function Changes in chapter Maintenance. 1.
