Memu Operation

User’s Manual

1. The battery is not charged in the factory,please charge the battery

under the environmental temperature 5 - 40℃ before using.

2. After purchasing or long-term storage(more than two months),

charging the battery for the first time can not reach its saturation

capacity,repeat charge/discharge for twice or three times to make

battery capacity achieve the best state.

3. Before charging,please power off the transceiver,using the

transceiver during charging may affect correct charging.

4. If the battery has been charged fully,please do not charge it again,

otherwise the service life of the battery may be shorten or may be

damaged.

5. If the service time is significantly reduced even after completely

correct charging,the battery can not be used any more,please

replace a new battery.

Charging the Battery Pack

● Scanning

It is convenient for the user to search for calls from other channels.

When【Channel-】is programmed to the scanning function, long

press【Channel-】key for two seconds to enter into the scanning

mode; operate it again or switch the channel to exit.

● Keyboard Lockout

Press both【Channel+】【Channel-】keys to lock all buttons,

operate them again to unlock.

● Monitoring

This operation is used when you wish to adjust the volume level or

Optional Functions

if you need to receive signals that are weak.

Long press 【Channel+】 key for two seconds to enter into the

monitor mode,release it to exit.

● Emergency Alarm

The purpose of the TOT is to prevent any single person from

using a channel for an extended period of time. An alarm will

sound if the transmission continues beyond the set time. The

transceiver will stop transmission if this occurs. To stop the

alarm, release the PTT switch and the transceiver will return to

standby.

● VOX

This function can be voice activated so the user doesn't have to

press the PTT key. Switch to Channel 7, turn 0ff the transceiver,

then press the FUNCTION KEY and【Channel+】key and turn

on the transceiver at the same time.

● Battery Power Saving

If there is no signal or operation, the radio will reduce its power

consumption. The battery power-saving function activates when

the channel is unoccupied or has not been in operation.

● Scrambling

It is a voice encryption mode which is different from sub audio.

● Low Battery Warning

If the battery power falls to the predetermined value during

transmission, the transceiver will give out a voice prompt, please

charge in time.

● Busy Channel Lockout

The function can prevent interference from other transceivers

using the same channel.

● Companding

It is a function setting which prevents the inter-channel

interference.

● CDCSS Mode

It is valid only when you program the CDCSS on the channels.

This function has two selections: "normal signaling" and "special

signaling". Normal Signaling refers to the CDCSS codes on the

channels is ordinary codes, we can talk to each other with the

same CDCSS; Special Signaling refers to the CDCSS codes on

the channels is special processed codes. When the transceivers

in one company are programmed the same frequency with the

same CDCSS and special signaling, they can avoid the signal

interferences from the other companies’ transceivers.

● CTCSS/DCS

The transceiver has 50 CTCSS and 208 DCS, also nonstandard

subaudio can be programmed! CTCSS function is used to avoid

mutual interference among various users and also to avoid

hearing irrelevant calls and interference signals. CDCSS is a

further development of the continuous tone-coded squelch system

or CTCSS that uses a slow-speed,binary data stream passed as

sub-audible data along with the transmission. It adds a tone into

your transmission at a certain frequency.

RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE FOR

PORTABLE TWO-WAY RADIOS

This two-way radio uses electromagnetic energy in the radio frequency

(RF) spectrum to provide communications between two or more users

over a distance. RF energy, which when used improperly, can cause

biological damage.

All Retevis two-way radios are designed, manufactured, and tested to

ensure they meet government-established RF exposure levels. In ad-

dition, manufacturers also recommend specific operating instructions

to users of two-way radios. These instructions are important because

they inform users about RF energy exposure and provide simple

procedures on how to control it.

Please refer to the following websites for more information on what

RF energy exposure is and how to control your exposure to assure

compliance with established RF exposure limits:

http://www.who.int/en/

Local Government Regulations

When two-way radios are used as a consequence of employment, the

Local Government Regulations requires users to be fully aware of and

able to control their exposure to meet occupational requirements.

Exposure awareness can be facilitated by the use of a product label

directing users to specific user awareness information. Your Retevis

two-way radio has a RF Exposure Product Label. Also, your Retevis

user manual, or separate safety booklet includes information and

Warnings

Before using this radio, read this guide which

contains important operating instructions for safe

usage and RF energy awareness and control for

compliance with applicable standards and

regulations.
