mode setting, the frequency shifting algorithm’s function will automatically

change as well.

NOISE REDUCTION FILTER (NRF): Incorporates a complex DSP algorithm

which filters out background noise while allowing the diver’s speech to be clear

and intelligible. Amron NRF automatically captures the frequency spectrum of

applied background noise within the audio frequency bandwidth and reduces it

without affecting the diver’s speech. The NRF has four adjustment levels for the

reduction of background noise in both depth modes A & B. When in mode A,

simply toggle the Mode Switch from A to B and back to A. In mode B, simply

toggle the Mode Switch from B to A and back to B. Each time a toggle cycle is

completed, the filter will advance to the next level. Based on the filter level, the

operator will hear a number of beeping tones from 1-4 that corresponds with the

blue LED indicators.

NRF INDICATOR: There are four blue LED indicators that correspond to the

present setting of the noise reduction filter ranging 1-4.

4.6.2 WIRELESS TENDER, /28A OPTION - This option is mounted in the right hand side

of the front panel. This Wireless Tender Option is for four-wire (Full Duplex)

operation only. System comes standard with a remote wireless tender module.

WIRELESS OPTION PANEL: Comes standard with antenna and power on/off

switch. The “ON/OFF” switch powers the wireless PC card inside the

communicator. The antenna has a swivel and tilt that allows the antenna to be

folded down during shipment. For operation, the antenna should be pointing

upwards. For installations where the Diver Communicator is located inside a

structure, there is an optional Remote Antenna kit available. This kit allows the

antenna to be located outside the structure for maximum effective range.

IMPORTANT: When the wireless option is not used, turn the option panel switch

to “OFF”. When option panel switch is turned “ON”, the wireless remote should

be “ON”. Otherwise a static noise may be heard through the communicator’s

panel speaker as it scans for available Remote Wireless Tender.

REMOTE WIRELESS TENDER MODULE: This module comes standard with an

internal rechargeable battery. Headset and external 110V charger jacks are

located on remote module.

ON/OFF-VOLUME CONTROL: Adjusts the listening volume and turns the unit

“OFF” when it is turned completely upwards.

TALK PUSH BUTTON: This button is located on the top of the unit and is labeled

TALK. When is first turned on, the remote wireless is in the Standby Mode (listen

only) as indicated by the LED closest to the button being red. When button is

press, the remote wireless is in the “Talk Mode” (listen and talk, full duplex) and

the LED is green. Pressing the TALK button toggles between the two modes.

Multiple Remote Wireless Tender Modules can be in the Standby (listen only)

mode at the same time. Only one module can be in the Talk mode.

HEADSET JACK: Located on the side opposite to the ON/OFF-Volume Control.

Plug the remote wireless headset to this Jack.

CHARGE JACK: Located on the side next to the ON/OFF-Volume Control. Plug

the remote wireless charger to this jack.
