IMPORTANT SAFEGUARDS
Read these instructions carefully and retain them for future use. If this product is passed to a third party, then these instructions must be included. When using electrical devices, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and/or injury to persons including the following:
CAUTION Damaged antenna! Do not use any Terrain 850 that has a damaged antenna. If a damaged antenna comes in contact with the skin, a minor burn may result.
WARNING
- For vehicles with an airbag! Do not place your Terrain 850 in the area over an airbag or in the airbag deployment area. Airbags inflate with great force. If a Terrain 850 is placed in the airbag deployment area and the airbag inflates, the Terrain 850 may be propelled with great force and cause serious injury to the occupants of the vehicle.
- To avoid possible interference with blasting operations turn the product off near electrical blasting caps, in a “blasting area” or in areas marked “Turn off two-way radios”. Obey all signs and instructions.
NOTICE Areas with potentially explosive atmospheres are often, but not always, clearly marked. They include fuelling areas such as below deck on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles, such as grain, dust, or metal powders, and any other area where you would normally be advised to turn off your vehicle engine.
Battery Warnings
- When placing the Terrain 850 in the charger, use only the electricity supply type provided with the Terrain 850.
- Do not try to recharge non-rechargeable batteries.
- Make sure the battery compartment cover is securely locked in place when you are charging the batteries.
- Do not leave dead batteries in your Terrain 850 units – they may leak.
CAUTION All batteries can cause property damage and/or bodily injury such as burns if conductive materials such as jewellery, keys, or beaded chains touch exposed terminals. The material may close an electrical circuit (short-circuit) and become quite hot. Exercise care in handling any charged battery, particularly when placing it inside a pocket, purse, or other container with metal objects.
WARNING Do not replace or charge batteries in a potentially explosive atmosphere. Contact sparking may occur while installing or removing batteries and cause an explosion.
Installation
Removing the Belt Clip
- Pull the belt clip latch forward (away from the Terrain 850).
- While pulling the belt clip latch, push up the belt clip as shown in Fig. 1.
Installing the Belt Clip
- Slide the belt clip into the slot as shown in Fig. 2. A “click” indicates the belt clip is locked into position.
Installing the Batteries
CAUTION Observe proper battery polarity orientation when installing batteries. Incorrect positioning can damage both the batteries and the unit.
- Unclip the battery compartment cover.
- Install the rechargeable batteries by following the orientation as shown in Fig. 3.
- Replace the battery compartment cover. See Fig. 4.
Charging the batteries – in the charge cradle
- Insert the Micro USB plug on the end of the mains adaptor into the power-in connection socket on the back of the desktop charger.
- Plug the mains adaptor into a 230-240 V~, 50 Hz mains socket with the switch on the socket set to OFF.
- Switch ON the mains socket.
NOTICE The Terrain 850 must be charged using the mains adaptor provided. Use of any other adaptor will result in non-compliance with EN60950-1 and will invalidate any approvals & the warranty.
- Place the Terrain 850 units in the charge cradle in an upright position and facing outward. The LED charge indicators will light up.
- It takes about 10 hours to fully recharge the batteries if they are completely run down. New batteries take up to 14 hours to fully charge.
NOTICE Always turn off the PMR units when charging. This will shorten the charging time.
Charging the batteries – directly from the adaptor
- Lift the charge socket cover located on the upper side of the handset.
- Insert the connector of the 5 V DC/400 mA mains adaptor into the powerin Micro USB socket in the side of the Terrain 850.
- Plug the mains adaptor into a 230-240 V~, 50 Hz mains socket with the switch on the socket set to OFF. Use only the electricity supply type provided with the Terrain 850.
- Then switch ON the mains socket.
Battery meter
- The battery meter is located in the left corner of the LCD screen.
- It has the appearance of a battery with three bars inside. These indicate the amount of power available. When the battery level is low, it will emit a “beep” sound every 10 seconds in normal mode.
- When the battery level reaches its minimum level in Terrain 850 ON mode, the unit will emit two beep tones and automatically turn off the power.
Important: Charge the unit for 10-14 hours.
CAUTION Risk of explosion! If battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.
- Battery life
- The Terrain 850 has a built-in power saver to make the batteries last longer. But when you are not using the units, turn them OFF to conserve battery power

- Batteries may be weak – recharge/replace the batteries. Range is limited.
- Batteries may be weak.
- Recharge the batteries or replace the old batteries with new ones if the charge level indicator gets low.
- See the “Effective Range” diagram. The maximum range will vary depending on terrain and environment.
- Open fields provide the maximum range, while steel/concrete structures, heavy foliage, and use in buildings and in vehicles may limit the range significantly.
- Wearing the radio close to the body, such as in a pocket or on a belt, will decrease the range; change the location of the radio. Sound distortion problems.
- If you are transmitting, speak in a normal tone of voice, 5 cm away from the MIC (microphone).
