MEMORY FEATURES

MICROPROCESSOR MEMORY BACKUP

This transceiver uses a lithium battery to retain the user- specified memory items. Switching OFF the power will not erase the Menu Setups or memory channels. Lithium battery life is approximately 5 years.

If you find the transceiver powers-up with default settings, and VFO and memory channel data is erased, have the lithium battery replaced. Contact an authorized KENWOOD Service Facility or dealer.

CONVENTIONAL OR QUICK MEMORY?

Memory channels allow you to save various operating parameters (receive frequency, operating mode, etc.) for recall at a later time. You can store this data in Conventional or Quick memory. Conventional memory is used for storing data that you may want to recall many times in the future during different operating sessions. For example, Conventional memory is useful to store the frequency where you regularly meet your club members.

However, Quick memory is meant for quickly saving data without needing to specify a particular memory channel. ItÕs likely that you wonÕt need this data during future operating sessions. For example, as you tune across the band looking for DX, it is convenient to store stations that you want to contact into Quick memory. You can quickly jump between several different Quick memory channels as you monitor them.

CONVENTIONAL MEMORY

MEMORY CHANNEL DATA

There are a total of 100 Conventional memory channels. The channels are numbered 00 ~ 99. Channels 00 ~ 98 have identical characteristics whereas channel 99 is reserved for programming VFO tuning ranges and scan ranges.

Channels 00 ~ 98 can store the following:

¥Receive frequency and mode

¥Transmit frequency and mode

¥Subtone frequency

¥Memory Lock Out (OFF/ON)

Note: The Subtone selected via Menu No. 57 (SUB.TONE) is automatically stored, but the stored Subtone can only be used if the TX and RX modes are FM.

Channel 99 can store the following:

¥Frequency and mode (simplex only)

¥Start frequency and mode

¥End frequency

¥Memory Lock Out (OFF/ON)

MEMORY CHANNEL STORAGE

Memory channels can be either simplex or split-frequency. Simplex channels use the stored frequency for receiving and transmitting. Split-frequency channels use a different frequency for transmitting and receiving. Also, even if RIT or XIT is ON with a frequency offset selected, this offset will not be added to the frequency when it is stored.

■Simplex Channels

1 Press [RX A] or [RX B] to select simplex mode.

¥The indicators in the [RX A] and [TX A] buttons, or the indicators in the [RX B] and [TX B] buttons must be ON.

2Select the frequency, mode, etc. to be stored.

3Press [M.IN] to select Memory Scroll mode.

AGC AUTO

M.CH

M. SCR

¥To exit from Memory Scroll mode and abort the storage process, press [CLR].

4Turn the M.CH/VFO.CH control to select a memory channel.

5Press [M.IN] to store the frequency and associated data in the selected memory channel.

¥Pressing [M.IN] overwrites your new data on any previous data in that channel.
