PRODUCT INSPECTION

Prior to unpacking the RDR42x0 series portable radio, please inspect the packaging for signs of damage and report any damage or missing components immediately to your RCA Communications System Sales and Service Center. Every RDR42x0 series portable radios should come with the following items:

Preparing Your Radio for Initial Use Setting Up Your Charger

1. Plug the adapter’s AC connector into the AC outlet socket. (see image A)
2. Plug the adapter’s DC connector into the DC socket on the back of the charger. (see image B)
3. Place the radio with the battery attached, or the battery alone, in the charger. (see image C)
4. Make sure the battery contact is touching the charging terminals. The charging process begins when the red LED light illuminates.
5. The green LED light will illuminate approximately two hours later, indicating the battery is fully charged.
   

 

Battery Information

Charging the Battery

Your radio is powered by a Lithium-Ion (Lilon) battery. To avoid damage and comply with warranty terms, charge the battery using only an original RCA charger, exactly as described in the charger user guide. When the charger’s LED illuminates red, it is an indication that the battery is being correctly charged. When the LED illuminates green, the battery charge is complete.
Note: Charge a new battery 12 to 14 hours before initial use for best performance. Maximum battery capacity is normally achieved after two or three full charge / discharge cycles.

Caution: To reduce the risk of injury, use only batteries specified by RCA Communications Systems.

• To avoid risk of personal injury, do not dispose of batteries in a fire. – Dispose of batteries according to local recycling regulations. Do not dispose as household waste. –
• Never attempt to disassemble the battery.
• When charging a battery, keep it at a temperature between 41°F ~ 104°F (5°C ~ 40°C) to ensure a full charge. Temperatures outside this range significantly reduce battery life. The operating time (talktime and standby time) is noticeably shorter than normal, replace the battery.
• Before charging a battery attached to a radio, turn the radio off to ensure a full charge. Never leave a radio on while in the charger, as it can damage both the battery and the radio; the charger is not a radio stand.
• Do not cut off the power supply or remove battery while charging.
• Never charge a battery that is wet. Dry it with soft cloth prior charging.
• The battery will eventually weaken. When the operating time (talktime and standby time) becomes noticeably shorter than normal, replace the battery.
• Battery performance greatly decreases at temperatures below -4°F (-20°C). Having a spare battery is always necessary in extremely cold environments. A cold battery may work again when it returns to room temperature, so keep it for later use.
• Dust on the battery contact may cause the battery not to work or charge properly. Use a clean dry cloth to wipe it before attaching the battery to the radio.
• Batteries with damaged contacts can be extremely dangerous. Any battery with damage to one or more contacts should be replaced immediately and not used under any circumstances.

Battery Storage

1. Fully charge the battery before storing it for an extended period of time to avoid battery damage due to over-discharge.
2. Recharge a battery after three months storage to avoid reduced battery capacity due to over-discharge.
3. When storing a battery, keep it in a dry place at room temperature.

Attaching/ Removing the Battery

1.  To install the battery, please place it into the groove on the top of the radio chassis about 5mm away from latch. If the radio has the belt clip installed, you will have to press one side of the clip to raise it and then slide the battery in proper position. Press the battery with your fingers and push the battery until you hear a latch click. The battery is now installed. (See Figure 1)
2. If you want to remove the battery from the radio, first press the battery latch located on the bottom of the radio, and then press down to slide the battery about 5mm to release the latch. (See Figure 2)

Attaching the Antenna

Screw the antenna into the connector at the top of the radio by holding the bottom of the antenna and turn it clockwise until secure. (See Figure 3)

Attaching / Removing the Belt Clip

Use the 2 screws (M2.5×8.0) supplied with the radio and insert these screws through the holes in the radio clip and into the holes in the aluminum case. If you want to remove the clip from the radio, just unscrew them, and remove the clip. You can put the screws back into the radio to make sure you do not lose them. (See Figure 4)

Connecting Audio Accessories

Open the cover of the connector for external speaker/MIC, and then insert the plug of the external speaker or microphone onto the connector socket of the radio. When screwing the accessory plug, make sure it is properly aligned (straight) to ensure the right connection to the connector of the radio. (See Figure 5)

Turn On/Off the Radio

1. Rotate the On/Off/Volume Control Knob clockwise until you hear a click. The LED blinks orange and a brief tone sounds, indicating that the power up test is successful. The RDR4250 & RDR4280 radio displays “RCA RDR42X0 DMR Radio” when powered up.
2. To turn off the radio, rotate the knob counterclockwise until you hear a click.
