Page 3: Introduction
BRU1 Presentation Base Radio Unit 1 (BRU1) is a complete one-channel compact radio base station which uses 8 kbps data signalling. The BRU1, which is intended for indoor operation, is a link between the mobile terminals and the area exchanges in the Mobitex Network. -
Page 4: The Bru1 Delivery Specification
Standard Installation Equipment The BRU1 is delivered with an installation bracket which comprises all the parts needed to install the BRU1 on a wall, except for the installation material listed in chapter 4.1 “Not Included Installation Material (Provided by the Installation Contractor)”. -
Page 5: Site Requirements
For safety reason it is important that users cannot touch the antenna or approach the antenna near field. If another antenna than the delivered is used, please keep in mind that the BRU1 is an indoor equipment only. Do not mount the antenna outdoor, where it can be exposed to lightning. -
Page 6: Maintenance
- Connect the equipment into an outlet with a separate circuit (if an AC/DC converter is used). Maintenance For maintenance reason it is important to have easy access to the connectors. Please follow the recommendations in this chapter. BRU1 MANUAL, Doc.no: b1sitreq Uen Rev PA5, 2004-02-19... -
Page 7: Space Required
SITE REQUIREMENTS AND INSTALLATION INSTRUCTIONS 7 (28) Space Required When deciding where to install the BRU1, it is important to keep the following in mind: • The BRU1 must be installed where the delivered antenna gives a good indoor coverage. -
Page 8: General
The space specified in this document is a minimum to allow an adequate airflow around the equipment. The customer decides if any additional working space is needed around the BRU1. The BRU1 can be mounted in two directions, either with the antenna facing up, or with the antenna facing down. The building material in the walls and ceiling may interfere with the antenna and the position of the BRU1 must therefore be made carefully. -
Page 9: Preparations Before Installation
SITE REQUIREMENTS AND INSTALLATION INSTRUCTIONS 9 (28) Preparations Before Installation Generally, the BRU1 can be installed at most indoor locations. However, it is important that the BRU1 is always mounted for optimal indoor coverage and good ventilation. On delivery, all mounting components except screws are delivered together with the BRU1. -
Page 10: Site Inspection
Check that all cables provided by the customer are in position and ready to be connected to the BRU1. • Check that the site network connection has been routed to the BRU1. BRU1 MANUAL, Doc.no: b1sitreq Uen Rev PA5, 2004-02-19... -
Page 11: Installation Of The Bru1
Installation of the BRU1 Installation of the BRU1 on a Wall Unpack the BRU1 equipment. Tick off all parts against the delivery note. Please report missing or damaged parts to the shipper. Mark the positions of three holes using the base plate. Drill the three holes in the wall with an appropriate dimension, see Figure 4. - Page 12 Figure 4 BRU1 base plate dimensions. Install the base plate on the wall (type of screws and plugs depends on the wall material and the BRU1 weight of 4 kg.). Note: Base plate measurements are given in millimeters.

Warning: If the delivered antenna is replaced or relocated with an antenna device with different characteristics please follow the instructions given in chapter 3.3 “RF Environment”.
- Page 14 14 (28) BRU1 MANUAL Lift the BRU1 (see Figure 6). Put the two hook-up plastic wheels (B) into the openings in the base plate and let the BRU1 slide down into position. Figure 6 Mounting instruction. Fasten the locking pin (C).
