FOR FIXED USE
1. Avoid installing the unit in places exposed to rain, water splash, direct sunshine, dust, vibra-
tion, or heat. |
2. An external antenna should be used for indoor operation. The use of the whip antenna in-
doors may cause TVI, BCI, Hi-Fi interference, malfunction of stabilized DC power supply,
etc. When using an external antenna, be sure to collapse the telescoping antenna into the
body.
3. For fixed use, an external power supply is more economical than batteries.
4. Use of the linear amplifier IC-SOL, and AC power supply IC-3PS, give excellent performance
for fixed use.
HOW TO USE EXTERNAL ANTENNA
Select a high performance antenna (a multi-element beam or gain antenna) and set it up in the
highest possible position. Tightly connect the antenna so that performance will not be affected by
weather or vibration. The matching impedance is designed to be 50 ohms.
