Cautions:

•Avoid routing the cable next to sharp edges or moving parts which might dam- age the cable.

•Do not run the cable next to power cables or other radio antenna cables.

•Do not run the cable through a vehicle’s engine compartment or other areas that produce extreme heat.

To take advantage of your radio’s maximum range, adjust the antenna’s Standing Wave Ratio (SWR) using an SWR meter, available at your local RadioShack store.

Follow the instructions supplied with the SWR meter and antenna to adjust your an- tenna’s SWR to the lowest possible value. SWR values of 2.0:1 are generally accept- able, with readings of 1.5:1 or lower being more desirable.

MICROPHONE
