1.5 Junction Box DS-640 (option)
Installation considerations
The junction box forms a joint between the distributor and the transceiver unit, and extends the
distance between them to max. 500 m. Install it as below:
• Keep the junction box away from noise-emitting electrical machinery, for example, electric gen-
erator, radio transmitter and TV.
• Do not install the junction box in place of high temperature and humidity.
See the outline drawing at the back of this manual.
