Programming software

Thanks to the Midland Programming software PRG-G10, it is possible to increase the performance of your radio or to reduce its functionality by enabling or disabling some features.
For further information, please consult the Programming software manual. When programming the transceiver, read the factory initial data first, then rewrite the frequency and signaling etc., otherwise errors may occur because of different frequency band etc.

Charging Operation

The battery is not charged at the factory, please charge it before use. Charge the battery for the first time after purchase or extended storage (more than 2 months) may not bring the battery to its normal operating capacity. After repeating fully charge/discharge cycle for two or three times, the operating capacity will reach the best performance. The battery life is over when its operating time decreases even though it is fully and correctly charged. Replace the battery

Battery Charger Type

Please use the original charger by Midland; other models may cause explosion and injure people. After installing the battery, if the radio red light twinkles, it means that the battery is discharged; please charge it. .

Charging notes

• After the battery is charged to its highest capacity, don’t charge anymore.
• Do not short-circuit the battery terminals or throw the battery into fire.
• Never attempt to remove the casing from the battery pack.
• Please turn the power off before charging. It will affect the battery life when charging the power-on radio.
• If the radio still shows low power after the normal charge, please change the battery.
• The average usage time of battery pack is 11 hours. Average usage time is 5% for transmitting, 5% for receiving and 90% for standby.

How to Charge

1. Plug the AC adaptor into the AC outlet, then plug the cable of AC adaptor into the DC jack, the indicator lights orange for 1s and turns into GREEN- –waits to charge.
2. Slide the battery or transceiver with battery into the charger; make sure the battery terminals are in contact with the charging terminals well. LED turns into twinkling RED—pre-charging begins.
3. Pre-charging for about 5 minutes, LED twinkles stop then charging begins.
4. It takes about 4 hours to fully charge the battery, when LED turns into GREEN — fully charged.

NOTE: When charging a power-on transceiver equipped with battery, the LED will not turn into green to show the full charge status; it will be indicated only when you turn off the transceiver: because when the transceiver is turned on, it would consumes energy and the charger cannot detect when the battery has been fully charged.

Charging Process:

Standby (self-examine orange lights 1 second when power on)| Green light
Pre-charging (pre-charging stage)| Red light twinkles for about 5 minutes
Charging| RED light lightens for about 4 hours
Full charged| Green light
LED Indicator:

STATUS| LED
Self-examine when power on| Orange (for 1 second)
(No battery)| Green
Pre-charging| Red light twinkles for 5 minutes
Charge normally| Red
Full Charged| Green
Trouble| Red twinkles for a long time

NOTE: Trouble means battery heating, battery short-circuit or charger shortcircuit.

Charging Prompt

1. Self-examination : When charging, ORANGE light twinkles for 1 second and goes out. That means the charger has passed its self-examination and it can charge the battery normally. If the light remains orange or the red light twinkles, which means the charger can not pass its self-examination or charge the battery.
2. Trickle pre-charging : When the battery has been inserted into the charger and red light twinkles (it means the remnant voltage is low), the charger trickle charges the battery (pre-charging status), until the battery reaches a certain electric quantity, the charger automatically turns into normal charging. And if the red light stops twinkling, (it means the remnant voltage meets a certain electric quantity), the charger will charge the battery normally.

NOTE: The time for Trickle pre-charging does not exceed 30m. After 30m, if the red indicator is still twinkling, it means it is unable to charge battery. Please kindly check battery and charger.

How to Store the Battery

If the battery needs to be stored for a long period, the battery should be removed from the radio. Its state of charge should be 50-100% charged. It should be kept in low temperature, dry environment. Kkeep away from hot places and direct sunlight.

Warning

• Do not short circuit battery terminals.
• Never attempt to remove the casing from the battery pack.
• Never assemble the battery in dangerous surroundings, spark may cause explosion.
• Do not put the battery in hot environment or throw it into fire, it may also cause explosion.

Basic Operations

Turn the Radio On & Off

In power-off state, please turn POWER/VOLUME clockwise to turn on the transceiver.
In power-on state, please turn POWER/VOLUME anticlockwise to turn off the transceiver.

Adjusting Volume

In power-on state, turn POWER/VOLUME to adjust the volume. Clockwise-up, anticlockwise -down.
When adjusting the volume, press the key programmed as Squelch Off to monitor the current volume firstly.

NOTE: Press the side key programmed as Squelch Off Momentary to monitor the background noise. Turn POWER/VOLUME to control the volume. The desired volume can be adjusted more correctly when communicating with the other parties.

Switch between Main band and Sub band

In standby mode, press the MAIN key to switch the channel between the Main band and Sub band. The arrow indicates the current operational channel.

Switch between Channel mode and VFO mode

In standby mode, press the V/M key to set the main band as Channel mode or frequency mode(VFO).

Channel Adjusting

When the transceiver is set in Channel mode or FM radio channel mode, rotate the channel switch to select the channel. Rotate the channel switch clockwise to enter the downward channel, counterclockwise to enter the upward channel.

NOTE: In transceiver mode, the arrow indicates the main band channel. If there is a null channel between two channels, the transceiver will skip it and will enter into the next channel directly.

Frequency Adjusting

When the transceiver is set in VFO mode or FM radio frequency mode, rotate the channel switch to set the frequency. Rotate the channel switch clockwise to increase the frequency, counterclockwise to decrease the frequency. Every rotate can add or reduce one stepping value.
NOTE: Channel step:2.5K, 5K, 6.25K, 10K, 12.5K, 20K, 25K, 30K and 50KHz in total 9 for optional. FM radio step frequency is 50K.

Frequency Input by Keypad

In frequency mode or FM radio frequency mode, you can directly enter the frequency through the keypad. When your transceiver is under Channel mode, press the V/M key to switch into VFO.
NOTE: When the transceiver is in Channel mode, it shows the current channel number on the right of the main frequency. Enter the desired frequency by keypad.
NOTE: The frequency input of main channel or FM radio is relevant to the stepping and transceiver frequency range. If the frequency setup is beyond the range or does not match with the step size, the input is unavailable. Under the FM radio mode, the frequency step size input by numeric keys is 100k.

Channel Input by Keypad

In channel mode or FM radio mode, you can switch to the desired channel by entering three numbers (001-199). If the entered channel is not in edited channel range, the transceiver will emit a beep to warn about the wrong input and return to the current channel. For example, entering 001 is channel 1, 030 is channel 30, 125 is channel 125.
