Turning on the CS90 to Passive mode
In order to use the CS90, you must first turn it on. In this situation we do not want the CS90 to transmit, so we will leave it in Passive mode.
Prerequisites
This procedure assumes that the entire CS90 installation has been inspected. All power sources have been measured and verified. All system cables and connectors have been checked and tested.
Note
The transceiver plug is not connected to the Transceiver Unit.
Context
The CS90 program starts automatically when the Processor Unit is turned on.
Caution
You must never start CS90 transmissions ("pinging") when the ship is in dry dock. The transducer may be damaged if it transmits in open air.
Procedure
1 Turn on the display.
If required, refer to the instructions provided by the display manufacturer.
2 On the Operating Panel, press Power, and keep it depressed for a few seconds.
Wait while the operating system and CS90 program is loaded and started. Both the Processor Unit and the Transceiver Unit are turned on automatically.
3 Once the CS90 program has started, observe that the presentation fills the entire screen.
4 In the bottom right corner of the presentation, observe the small green indicator.
Image
This indicator flashes to show you the progress of the start-up sequence. When the green light is steady, the CS90 is ready for use. If you wish to monitor the start-up sequence, double-click the indicator to open the Transceiver On/Off dialog box.
Note
When the transducer plug is disconnected it will turn green, but you must not start the transmissions.
5 At the bottom of the Main menu, observe that the Operation menu icon is flashing.
It is flashing to indicate that even if the CS90 is turned on, "pinging" is disabled. The CS90 is in Normal mode, but TX Power is set to Off to prevent transmission. This is for safety reasons.
