NRC ENOS Trans m

The ENOS transmitter ETX is pressure-tight to 100 m (330 ft) and is supplied with a Cordura bag and carabiner. It transmits its signal every 20 seconds, so the crew always knows the diver's current position. According to NRC, the short transmission intervals enable reliable transmission even in heavy seas.

• LED on the head flashes regularly during operation, is visible from a distance and shows battery level and operating mode
• Simple operation: to switch on, the red foot is turned through 180 degrees; there are no other switches
• After switching on, the asymmetric switch position clearly shows ON
• Then hold the transmitter up; this can also be done with a diving buoy
• Range of up to 10 kilometres (5.6 NM), depending on the mounting height of the radio receiving antenna on board
• Powered by AAA lithium batteries, which are available worldwide and can be changed by the user
• Running time of 170 hours
• NRC states a capacity guarantee of 18 years for the batteries

NRC explains its use of batteries instead of rechargeable batteries by saying that rechargeable batteries lose power even when unused, have to be charged regularly, and an unnoticed power failure can affect their capacity. The flashing signals of the LED show when the batteries need changing, as described in the operating instructions.
