Note. Radiodetection receivers detect almost all buried cables and most conductors. However, some cables and
conductors do not radiate signals and cannot be detected by Radiodetection receivers. Radiodetection
receivers do not indicate whether a signal is from a single cable, several cables buried side by side or one
cable above another.
The operation of any cable and pipe locator may be adversely affected when used in close proximity to
ferrous materials such as manhole covers and parked cars. Keep a two-metre/six feet distance from these
objects when taking critical measurements such as depth and current. Standing too close to the receiver if
you are wearing steel toe capped boots may also affect the readings
WARNING. This equipment is NOT approved for use in areas where hazardous gases may be present.
WARNING. When using the RD4000 receiver reduce audio level before using headphones.
Dispose of batteries in accordance with your Company's work practice, and the relevant law or guidelines in
your country.
Caution: If the equipment is used in a manner not specified by Radiodetection, the protection provided by the
equipment may be impaired.
The RD4000 system is for use by suitably trained operators only.

PREPARATION FOR USE
RD4000 receiver
This section describes the available RD4000 receiver power supply options and gives instructions on fitting,
replacing, and charging batteries.
The RD4000 receiver is powered by four D-size (LR20) alkaline batteries or by anoptional rechargeable battery
pack.
Internal alkaline batteries
The four batteries are housed in a battery tray, which slots into
the front of the receiver. The tray is clearly marked with the
correct battery orientation.
Fitting and replacing alkaline batteries
Warning. Do not mutilate, puncture, or dispose of batteries by placing them in a fire. The batteries can
burst or explode, releasing hazardous chemicals.
Discard used batteries in accordance with the manufacturer’s instructions and your local regulations.
Caution. When replacing batteries always ensure that the correct type of batteries is fitted.
Keep the battery tray dry whilst changing the batteries.
• To remove the battery pack tray, place your fingers under the battery pack release catch, and pull the
battery pack towards you from the RD4000 housing
• Remove the batteries and dispose of them in accordance with local regulations
• Fit new batteries in accordance with the polarity diagram in the battery housing
• Insert the battery pack tray into the RD4000 battery pack housing and push the battery pack tray until it
clicks into the housing
• Switch the receiver on. If the display does not illuminate, ensure that the batteries are correctly oriented.
Note: To ensure maximum performance from the RD4000 receiver always replace the batteries as a set.
Rechargeable battery pack
The rechargeable battery pack is an interchangeable replacement for the standard battery pack and is supplied
complete with four Nickel-Metal-Hydride (NiMH) rechargeable batteries.
Fitting the rechargeable pack

Charging rechargeable batteries
Caution. If the batteries are being recharged from a vehicle cigarette lighter and the vehicle is being
driven, the battery packs must be removed from the transmitter or receiver whilst charging
takes place.
Do not use the receiver while the battery pack is being charged with the battery pack fitted to
the receiver.
Note: When charging batteries for the first time, charge them for 16 hours regardless of the indicated battery
level.
The rechargeable battery pack can be recharged via a vehicle cigarette lighter or via a mains power adaptor
with the pack fitted to the receiver or with the pack removed. However, we recommend that you remove the
battery pack from the receiver for recharging, particularly in hot ambient conditions. This will increase the post-
charge battery capacity and enhance overall battery life. Ideally, the battery pack should be charged at an
ambient temperature of between 00 C and 300 C.
To charge the batteries, remove the rubber protection cover from the front of the battery pack housing and plug
the charger lead (supplied) into the receiver connector. Plug the other end into the vehicle cigarette lighter
socket or plug the mains power adaptor (contact Radiodetection for adaptor details) into an appropriate power
supply and switch the power supply on. Follow the manufacturer’s instructions for operating the charger. When
charging is finished ensure that you re-fit the rubber protection cover.
Note: It is normal for the battery pack to become warm during charging.
RD4000 Rx Battery Charging LED Indications
Under normal charging conditions, the battery charge status indicator LED illuminates and is coloured red. Once
the batteries have finished charging the LED colour changes to green to indicate that charging is complete.
If the battery pack is completely discharged, or has been left in hot ambient temperatures, and the batteries
have become hot, the LED will flash red/green as soon as the battery charger is plugged in and may continue to
flash for sometime. In the case of a hot battery pack, the LED will turn red once the battery pack has cooled
down, indicating that the batteries are charging normally. The LED will turn green once charging is finished.
If the LED is flashing red/green because the batteries are completely discharged, the LED will continue to flash
red/green and trickle charge the batteries until they have reached a pre-determined charge level. The LED will
then turn red, indicating that the batteries are charging normally. The LED will turn green once charging is
finished.
The battery pack can be safely removed from charge at any stage in the charging cycle without affecting the
battery life. However, the batteries will only be partially charged.
The rechargeable batteries are not replaceable. If a fault occurs with the rechargeable battery pack, it must be
returned to Radiodetection for repair.
