FCC Information

FCC RF EXPOSURE COMPLIANCE REQUIREMENTS FOR OCCUPATIONAL USE

ONLY

◇ The Federal Communications Commission (FCC), with its action in General

Docket 93—62,November 7,1997,has adopted a safety standard for human exposure to Radio Frequency (RF) electromagnetic energy emitted by FCC regulated equipment. HYT subscribes to the same safety standard for the use of its products. Proper operation of this radio will result in user exposure far below the Occupational Safety and Health Act(OSHA) AND federal Communications

Commission limits.

◇ This radio is NOT approved for use by the general population in an uncontrolled environment. This radio is restricted to occupational use, work related operations only where radio operator muse have the knowledge to control the user’s exposure conditions for satisfying the higher exposure limit allowed for occupational use.

◇ When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm) away from your mouth. The radio is transmitting when the red LED on the front of the radio is illuminated. You can cause the radio to transmit by pressing the PTT bar on the radio.

◇ DO NOT transmit for more than 50% of total radio use time 50% duty cycle).

Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. These are required operating configurations for meeting FCC RF exposure compliance. Failure to observe these restrictions mean violation.

◇ This equipment complies with the FCC RF Exposure Limits for controlled environments.

Time-out Timer

Time-out Timer is used to prevent one from using the same channel for a long time and to prevent the radio from damage due to continuous transmission.

If the transmission exceeds preset time (it’s set by your dealer), transmission will be stopped and a beep will sound. To stop the beep tone, release PTT. Press PTT again to transmit.

TOT (Time-out Timer) Reset Time

When this feature is disabled, TOT is immediately reset after transmission stops. When enabled, TOT won’t reset until preset time (it’s set by your dealer) elapses, even if transmission has stopped.

TOT Rekey Time

The feature is used to set the duration until transmission is allowed after returning to receive by TOT. When enabled, transmission will be prohibited until preset time elapses

(it’s set by your dealer).

TOT Alert Time

This timer can be set by your dealer from 1 to 255 seconds in 1 second step. When this feature is enabled, the radio will call an alert at the set time. Transmission will be prohibited by TOT after this time.

Battery Save

CTCSS & CDCSS

CTCSS/CDCSS allows you to ignore unwanted calls from other parties using the same channel.

When CTCSS/CDCSS is set, the user can only receive the calls on the same channel with same CTCSS/CDCSS.

The dealer can preset CTCSS/CDCSS signaling on certain channels.

Note: Although using CTCSS/CDCSS enables you to avoid hearing unwanted calls, it does not mean your calls will be private.

Channel Scan (This feature can be disabled by your dealer)

Turn channel selector knob to the position “16”, the radio will automatically detect those channels which have been programmed as scan items in channel 1-15 (your dealer can set any channel as scan item or non-scan item). When any activity is detected on one channel, the radio will stop on the active channel for communications.

Priority Channel Scan

Any programmed channel may be set as the priority channel. The radio will detect the priority channel periodically while stopping on a non-priority channel. When there is any activity on the priority channel, the radio will turn to the priority channel for communications.

Scan Revert Channel

When the radio is scanning, press the PTT key, it will transmit in pre-programmed revert channel.

Revert channel can be programmed by your dealer.

Busy Channel Lockout

If the current channel is set by your dealer as “busy channel lockout”, and this channel is being used by other users, press PTT, the radio sounds a beep and will not transmit the signal. To stop the beep, release PTT. When this channel is free, press PTT to transmit.

Troubleshooting Guide

Trouble

No power

Solution

*Battery may be used up. Please recharge or replace the battery.

*The battery may not be properly installed. Remove the battery and attach it again.

Power doesn't last long even if fully charged

*Battery life is over, please replace it with a new one.

Can't talk to or hear group members *Make sure you are using the same frequency and same

CTCSS/CDCSS as your group members.

*Your group members may be out of the communication range.
