10 messages with a total playing time of 132 seconds. Up to three additional memory modules (MSM6685AJS from OKI Semiconductor, contact Philips CSI Sales Support for availability) can be added to the RMM printed circuit board to increase the total playing time to 528 seconds.
Caution: The RMM is designed to operate safely in a SM 25B Booster Frame or MXF. Ensure that the Booster Frame or MXF is installed in accordance with the Installation Instructions supplied with the equipment before installing the RMM. Supplied with the RMM (LBB 2541/10): • Installation and User Instructions Special tools required: •...
Connecting the RMM Caution: When wiring inputs to the RMM in a 19-inch rack, ensure that the cables are of sufficient length to allow the Booster Frame to be withdrawn on its runners (approx. 30 cm, 12 in.). Connecting RMM inputs/outputs Inputs from the GMM/MIX or CS-B are connected via the SM 25B system bus.

Note: Changes in configuration settings for each message only take place after pressing the ‘UPDATE’ button (S8, figure 1.13) while the RMM is in record mode. The display will show a ‘U’ when the ‘UPDATE’ button is pressed. Priority selection for messages Each message recorded can be assigned a priority from 1 (lowest) to 5 (highest).
(with remote switching contacts) should be used with the GMM/MIX set to mix-on-demand or priority mode. Two Philips microphones are available (LBB 9521/10 and LBB 9518/10) with a ded- icated LED indicator and switch to show system status. Any messages recorded using the GMM/MIX will be distributed to the SM 25B system bus, and will therefore be distributed to the selected zones while recording is taking place.
Note: The red mode indicator LED (item 3) will flash while a message is being recorded. 7. When the message is complete, stop the recording using the start/stop button (item 7) or the microphone switch. The red mode indication LED will stop flashing (but remains on). Note: If the memory for the message being recorded becomes full, the RMM automatically stops recording, and the red mode indicator LED stops flashing (but remains on).
Note: If a message is empty, the message number flashes alternately with a ‘-’ symbol. Playing back a message Playing a message remotely To play back a message remotely: 1. Ensure that the remote connections for the required message(s) is made on the connec- tor (item 1, figure 1.3) on the rear panel of the RMM.
