Section 7 - Install the Explorer 721

7-1 Installation Options

There are two ways to install the radio. You can choose:

•a deck or overhead mounted gimbal installation. The reversible mounting gimbal is fixed to to a suitable site and the radio is placed into it. The radio can be removed for storage and the viewing angle can be adjusted.

•a recessed installation. The radio is recessed into a cavity cut into a bulkhead. The radio fixture is permanent and the viewing angle cannot be adjusted.

NOTE: An optional handset with a 9.8` (3 m) docking cable included can be purchased and connected to your Explorer 721 base unit to give second station operation and intercom capability. The optional 701US handset (for the Explorer 721US) and the optional 701EU handset (for the Explorer 721EU) are shown on the front cover.

7-2 Location Requirements

Please check these BEFORE doing any cutting or drilling.

Whichever installation method you choose, ensure that the chosen location:

•is at least 3' (1 m) from the antenna

•allows easy connection to (at least) a 10 Amp fused 13.6 V DC electrical source and the antenna

•is at least 1.5' (45 cms) from the compass to avoid creating magnetic deviation of the compass during radio operation

•has a suitable space close by for installing the microphone bulkhead mount

•provides easy access to the controls on the front panel

•provides enough room to fix the DSC warning label (721US only).
