routine maintenance on the scanner or nearby equipment.
Introduction

remove the rear cover of the multi-function display or the
external cover of the Digital Radome scanner. There are no user serviceable
parts or adjustments.

Maintenance
Maintenance is limited to the following periodical checks:
• Examine the cables for signs of damage, such as chafing, nicks and
cuts. If the connector is showing signs of corrosion, lightly grease the
threads of the connector with “Renolit Aqua 2 Calcium” grease.
• Check that the cable connectors are firmly attached.
• Make sure the scanner is still securely attached to the mounting
surface.
• Once a year, remove, grease and re-attach the mounting bolts securing
the scanner.
