Introduction to the NORMARC 7710 NAV Analyzer The NORMARC 7710 NAV Analyzer is used to adjust, verify and record parameters of ILS (Localizer, Glide Path, Marker Beacon) and VOR ground systems. The NAV Analyser’s functionality substitutes instruments like ILS/VOR receivers, modulation meters and frequency counters. It incorporates all ILS and VOR channels selectable without any tuning or equipment changes.

5.6 How to connect to a computer through the network interface The instrument has a built-in web server that can be accessed through the LAN connector at the back. A connection can either be done directly to a computer or to a computer via a network with DHCP server. When connecting directly to a computer, the NORMARC 7710 may be set up as a DHCP-server, thereby simplifying the connection.
5.6.2 Connecting directly to a computer (Win XP) In the browser used for connecting to the instrument, turn off the use of Proxy servers. In IE this can be done by Tools – Internet Options – Connections – LAN Settings... and deselecting the Proxy server box.

Maintenance, calibration and software updates 7.1 Maintenance 7.1.1 Batteries The battery pack is rechargeable. When the batteries are worn out or damaged, they should be replaced. To do this, remove the back cover (see fig) and replace the batteries with equivalent types (NiMH, size D, rechargeable 10.000mAh).
Page 56
Self discharge When NiMH batteries have not been used for a long time they will self-discharge. The voltage on the cells will typically be < 1.0V. To fix this, restart the charge cycle once every five minutes a few times. Turning off and on again the external power restarts the charge cycle.
Page 57
IMPORTANT NOTE!!! • Do not charge the batteries at high temperatures. This will reduce the life time and capacity of the batteries • Do not charge fully charged batteries. Every time the external power is connected, a new charge cycle will be initiated. If the batteries are never discharged, this repeated new charge cycle will eventually over-charge and damage the batteries.
The battery indicator on the instrument does not display the correct information when using alkaline batteries. Do not charge alkaline batteries! 7.1.5 Corrective maintenance Except for replacement of batteries, Northrop Grumman Park Air Systems should do all corrective maintenance. 7.2 Calibration The instrument as delivered from factory is ready for use.
7.3 Software Updates New functions and enhanced functionality may be added to the instrument by upgrading the software. Information about software versions and how to download them can be found on the company's web page or by sending a request to support at: normarc.support@no.parkairsystems.com The procedure for upgrading the software is as follows.
