Location and fixing of the transceiver
The ambient temperature around the transceiver should be maintained between -25°C and +55°C.
The transceiver should not be located in a flammable or hazardous atmosphere, such as in an engine room or near to fuel tanks.
The transceiver must be fitted in a location where it is at least 0.2m from a compass or any magnetic device.
The transceiver should be mounted in a location where the LED indicators are readily visible as they provide important information on the status of the transceiver.
Wi-Fi & Bluetooth enabled variants (B922/B924/B952/B954) will benefit from being installed near the center of the boat to provide a consistent signal across all areas. The construction of your vessel can also have an impact on performance. For example, metal structural bulk heads and roofing, power cables and reflective surfaces can reduce, and in certain situations block, the signal. Consider testing the reception to ensure you're happy before you mount the bracket and transceiver.
For optimum performance the transceiver should be mounted at least 0.5m away from other high power transmitting equipment like VHF radios.
There should be adequate space around the transceiver for routing of cables. See Figure 11 for details of the transceiver dimensions.

Figure 12 FLEXI-FIT bracket
The B900 Series uses a simple bracket system to make installation as easy as possible. Use the bracket as a template to locate the desired position of the transceiver and simply screw or stick (adhesive pads are also supplied) the bracket to your vessel and then click the transceiver into the bracket. The secure clip will hold the transceiver securely in even the most severe weather and wave shocks.
To unclip the transceiver no tools are required. Simply push the release clip on the bracket with a finger or thumb and carefully rotate the transceiver and lift off the bracket.
