HM-134 CONNECTIONS AND INSTALLATION
I HM-134 supplied accessories
Accessories included with the HM-134: Qty. q Connection cable (OPC-1000: 6 m). 1 w Mounting base... 1 e Microphone hanger... 1 r Screws (M3 16; tapping).. 5

I Installation

The optional HM-134 can be connected to the transceiver directly, as well as via the supplied connection cable for longer distance remote operation. The connector of the connection cable can be installed into a cabinet, wall, etc., as a built-in plug. For longer distance remote operation, the optional extension cable, OPC-999 (6 m; Connecting between transceiver and the connection cable), is available, and up to 2 OPC-999 can be added. q Insert the supplied cable into the external microphone jack and tighten the cable nut as shown below.
w To use the supplied cable as a wall socket, follow the below steps. e Using the mounting base, carefully mark off the 2 spots where the cable and screws will be fastened. r Drill holes at these marks. t Install the mounting base using the supplied screws as shown below.

INSTALLATION NOTES

I Installation notes
The installation of this equipment should be made in such a manner as to respect the EC recommended electromagnetic eld exposure limits (1999/519/EC). The maximum RF power available from this device is 25 watts. The antenna should be installed as high as possible for maximum efciency and that this installation height should be at least 5 meters above ground (or accessible) level. In the case where an antenna cannot be installed at a reasonable height, then the transmitter should neither be continuously operated for long periods if any person is within 5 meters of the antenna, nor operated at all if any person is touching the antenna. In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are specified as an average of 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts the transmitter after 12 minutes etc. Similarly some types of transmitter, SSB, CW, AM, etc. have a lower average output power and the perceived risk is even lower.
