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
af ter tw o or th r e e f ull charge / discharge cycles.
battery life. If the operating time (talk-time
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 (talk-time 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 a 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.
of the radio. It is used to connect RCA audio
accessories to the radio. Remove the accessory
cover by unscrewing the screw location at
the bottom of the cover. Connect the desired
audio accessory rmly into the accessory jack
and secure the screw by turning it clockwise.
(See Figure 6)
Note: Please loosen the
screw prior to removing
the audio accessory.
The use of the audio
accessory may affect

Push-To-Talk (PTT) Button
The PTT button on the side of the radio has
two main functions:
- Press and hold down PTT button to initiate
and call and talk. Release the PTT button
to listen. The microphone is activated when
the PTT button is pressed.
- If a call is in progress, the PTT button allows
the radio to transmit to the other radios
that are part of the call.
Note: If the Talk Permit Tone is enabled, wait
until the short alert tone ends before talking.
During a call, if the Channel Free Indication
feature is enabled on your radio (programmed
by your RCA Communications Systems Dealer),
you will hear a short alert tone the moment
the target radio (the radio that is receiving
your call) releases the PTT button, indicating
the channel is free for you to respond. You will
also hear the Channel Free Indication tone if
your call is interrupted, for example when the
radio receives an Emergency Call.
Switching Between Analog and Digital
Mode
Each channel in your radio can be programmed
as an analog channel or a digital channel. Use
the Channel Selector Knob to switch between
an analog or a digital channel.

RF Exposure Compliance and Control
Guidelines and Operating Instructions
To control your exposure and ensure
compliance with the occupational/controlled
environment exposure limits always adhere to
the following procedures.
Guidelines:
• Do not remove the RF Exposure Label from
the device.
• User awareness instructions should
accompany device when transferred to
other users.
• Do not use this device if the operational
requirements described herein are not met.
Operating Instructions:
• Transmit no more than the rated duty factor
of 50% of the time. To transmit (talk), push
the Push-To-Talk (PTT) button. To receive
calls, release the PTT button. Transmitting
50% of the time, or less, is important
because this radio generates measurable
RF energy exposure only when transmitting
(in terms of measuring for standards
compliance).
• Hold the radio in a vertical position in front
of face with the microphone (and the other
parts of the radio, including the antenna) at
least one inch (2.5 cm) away from the nose.
Keeping the radio at the proper distance is
important because RF exposures decrease
with distance from the antenna. Antenna
should be kept away from eyes.
• When worn on the body, always place
the radio in a RCA’s approved clip for
this product. Using approved body-worn
accessories is important because the use
of RCA’s or other manufacturer’s nonapproved accessories may result in exposure
levels, which exceed the occupational/
controlled environment RF exposure limits.
• If you are not using a body-worn accessory
and are not using the radio in the intended
use position in front of the face, then
TM
RDR1520 Series Professional Digital Two-Way Radio Instruction Manual
27Prodigi
ensure the antenna and the radio are kept
at least 2.5 cm (one inch) from the body
when transmitting. Keeping the radio at
the proper distance is important because RF
exposures decrease with increasing distance
from the antenna.
Use only RCA Communications Systems
approved, supplied or replacement antennas,
batteries, and accessories. Use of non-approved
antennas, batteries, and accessories may exceed
the FCC and IC RF exposure guidelines.
EXPOSURE RF compliance et Lignes de
contrôle et Instructions opérationnelles
Pour contrôler votre exposition et assurer
la conformité avec le milieu ambiant, il est
toujours nécessaire de suivre les procédures
suivies.
• Il ne faut pas utiliser cet appareil pour les
besoins opérationnels.
Description des opérations:
• La transmission ne dépasse pas 50% de la
valeur nominale. Pour téléporter (appel),
appuyez sur le bouton “Push – To– Talk”
(PTT). Pour recevoir un appel, libère le
bouton du PTT. La réduction de 50 % du
temps, ou moins, est importante, étant
donné que cette radio a été exposée à
la seule fois que la radioactivité de la
radioactivité a été utilisée en tant que
mesure de conformité.
• La radio est placée en face de face avec le
microphone (et les autres parts de la radio)
à moins d’un inch (2,5 cm). Le maintien de
la radio à distance est important car il est
important que les données soient tirées de
la distance.
