Getting Started

Channel Up/Down Button

Your radio will Receive (Rx) and Transmit (Tx) VHF and GMRS signals on the channel indicated on the LCD display. You can change the channel at any time using the Channel Up/Down button.

To Change Channels:

Press the Channel Up/Down button.

If you are on Channel 88, pressing the Channel Up button will advance to Channel 01. If you are on Channel 01, pressing the Channel Down button will advance to Channel 88.

You can press and hold the Channel Up/Down button for fast advance. The beep sound will occur only at the first press of the button and not during fast advance.

If the new channel selected is restricted to low power, the radio will automatically switch to Low Power mode and the Low Power icon will appear on the LCD.

If the radio is in the Key Lock mode, the channel will not change and the three (3) beep error signal will sound.

SCAN Button

Press and release the SCAN button to scan all channels. The SCAN icon will display on the LCD display. Scanning begins at lower channels, and scans to higher channels. Press Channel Up/Down button to change the scan direction.

When a signal is received in SCAN mode, the radio will pause 10 seconds before resuming SCAN operation. The scan will stop when the Talk button is pressed.

In Memory mode, press and release the SCAN button to scan all memory channels. Because the unit is already in the Memory Channel mode, only the channels in the memory bank will be displayed.

NOTE

Memory channels need to be saved to effectively enter the Memory Channel mode and scan all memory channels.

H-M-L Power Button

Call/Enter/Setup Button

Getting Started

High/Medium/Low (H-M-L) Power Button

Your radio can transmit selectively at 1, 3 or 5 watts of power. Cobra suggests you maintain the low power setting for short-range communications. You will conserve battery life and avoid overpowering nearby stations with a low power setting signal. Use the high power setting for long- range communications or when you do not receive a response to a signal sent at 1 watt.

To Toggle Between H-M-L Power Modes:

Press the H-M-L Power button. The LCD will show which mode is in effect. Some channels are restricted for a maximum use of 1 watt. Your radio will automatically set the power to Low Power mode when you select those channels.

NOTE

Some channels, frequency bands and countries of use might not be able to operate in High Power mode. For example, units sold in Canada will not transmit using the 5 watt High Power mode.

Call /Enter/Setup Button

The Call/Enter/Setup button has multiple functions. It is generally used in the following ways:

■Press and release to transmit your unique Call Tone signal to another radio.

■Press and hold to enter any Setup menu.

■Functions as an ENTER button when making a selection in any Setup menu.
