Power Adjust; Time-Out Timer (Tot); Battery Strength Indicator - HYT TC-300 Owner's Manual

Power Adjust

A press of the programmed Power Adjust key switches the transmit power level between
high and low power.

Time-out Timer (TOT)

Limits the amount of time the radio user can continuously transmit on a channel. This can
also protect your radio from damage due to excessive transmission. If the user holds
down the PTT longer than the preprogrammed limit, the radio automatically stops
transmitting, and generates a warning tone until the PTT is released.
Your dealer may program the alert tone that sounds before the TOT timer nearly expires.
Note: See Glossary for the definition of Time-out Timer.
