MODULE REPAIR SERVICE
During the transmitter’s warranty period, repair of modules is performed at no charge to the customer. Once the
warranty period has expired, module repairs will be invoiced based on material and labour costs.
MODULE EXCHANGE SERVICE (North American Customers Only)
North American customers can take advantage of Nautel’s module exchange service. This service gives customers
a fast and efficient solution in the event of a hardware problem. When a customer’s transmitter experiences a failure,
Nautel can send out a factory rebuilt module to replace the faulty module. Nautel’s two locations, Canada and the
United States, provide quick turn around times, keeping our customers on the air.
During the transmitter’s warranty period, exchange of modules is performed at no charge to the customer. Once the
warranty has expired, the cost of a module exchange is only 40% of the list price for the module, provided the faulty
module is returned to Nautel within 30 days and can be rebuilt; should the module not be returned an additional
invoice for 40% of the list price will be issued.
MODULE RETURN INSTRUCTIONS
All equipment being returned to Nautel for repair or replacement should be marked with a Nautel provided RMA
number and addressed to the appropriate Nautel facility.
Complete and accurate information regarding the equipment will expedite shipment of replacement(s). Refer to the

Safety Symbols
General definitions of safety symbols used on equipment or in manuals.
DANGER – HIGH VOLTAGE
Indicates dangerous voltages (in excess of 72 volts), capable of causing a
fatal electrical shock, are present on or near parts bearing this label.
GROUND (EARTH)
Used with wiring terminals to indicate the terminal must be connected to
earth ground before operating equipment. If power is supplied without
grounding the equipment, there is a risk of receiving a severe or fatal
electrical shock. Also used on electrical schematics to indicate a part that is
connected to earth ground.
GROUND (PROTECTIVE or SAFETY)
Used with protective (safety) conductor terminals to indicate the terminal
must be connected to ground before operating the equipment. If power is
supplied without grounding the equipment, there is a risk of receiving a
severe or fatal electrical shock.
ELECTROSTATIC SENSITIVE
Indicates a part or assembly is or contains devices that are electrostatic
sensitive. To prevent damage to these devices, ensure the handling
procedures outlined in this manual are observed.
WARNING A WARNING denotes a hazard. It identifies an operating procedure,
condition, etc. which, if not strictly observed or adhered to, could result in
injury or death to personnel. Throughout the technical manual, a
WARNING shall immediately precede the text to which it applies.
CAUTION A CAUTION denotes a hazard. It identifies an operating procedure,
condition, etc., which, if not strictly observed or adhered to, could result in
damage to, or destruction of the equipment. Throughout the technical
manual, a CAUTION shall immediately precede the text to which it
applies.
NOTE A NOTE denotes important information pertaining to an operating
procedure, condition, statement, etc., which is essential to highlight. A
NOTE may precede or follow the text to which it applies.

Artificial Respiration (Mouth-to-Mouth)
(a) START MOUTH-TO-MOUTH BREATHING IMMEDIATELY.
SECONDS COUNT. Do not wait to loosen clothing, warm the casualty, or
apply stimulants.
(b) ASSESS RESPONSIVENESS OF CASUALTY. Do not jar casualty or
cause further physical injury (Figure 1)
(c) IF POSSIBLE, SEND A BYSTANDER TO GET MEDICAL HELP. Do
not leave casualty unattended (Figure 2)
(d) CHECK CAROTID PULSE (Figure 3)
(e) LAY CASUALTY ON HIS/HER BACK and place any available jacket
or blanket under his/her shoulders.
(f) TILT THE HEAD BACK AND LIFT THE CHIN to open the airway
(Figure 4)
(g) PINCH CASUALTY’S NOSE AND EXHALE TWO SLOW BREATHS
INTO CASUALTY (Figure 5)
(h) REMOVE YOUR MOUTH and check for breathing (Figure 6)
(i) CONTINUE GIVING ONE BREATH EVERY FIVE SECONDS without
interruption. If any air is retained in the stomach after exhalation by
casualty, press gently on stomach to expel air.
(j) IF CHEST DOES NOT RISE, CHECK for obstruction in casualty’s
mouth: clear foreign material using your finger, tissues, etc. Use chin lift
and recommence mouth-to-mouth breathing.
(k) WHILE MOUTH-TO-MOUTH BREATHING IS CONTINUED have
someone else:
- Loosen casualty’s clothing.
- Keep the casualty warm.
(l) DON’T GIVE UP. Continue without interruption until the casualty is
revived, or until a doctor pronounces the casualty dead. Four hours or
more may be required.
(m) DO NOT PROVIDE ANYTHING ORALLY while victim is
unconscious.

General Rules for Treatment for Burns, Bleeding, and Shock
1. After casualty has revived, treat for injuries and shock.
2. Reassure casualty.
3. Try to make him comfortable.
4. Keep him reasonably warm but do not apply heat.
5. If thirsty, liquids may be given but no alcohol (no liquids should be given in cases of severe
burns).
6. Treat burns or wounds. Danger of infection when treating burns or wounds is very great, so
ensure hands are clean and do not handle affected areas more than necessary.
7. Do not apply salves, grease, etc. to burns.
8. Do not remove burned clothing that adheres to the skin or breaks blisters.
9. Cover the burn with a dry sterile dressing, piece of sheeting, etc.
10. Bandage lightly over blisters; care must be taken to cover and not to break the blisters.
11. If severe bleeding of wound, elevate affected area, except in the case of a fracture.
12. Expose wound and apply pressure.
13. Apply dressing, pad and bandage.
14. For burns and bleeding, immobilize injured part using splints, if necessary, and keep
patient in restful position during removal to hospital or expert medical attention.
15. In all cases, send for medical aid immediately.

V10/V7.5/V5/V3.5 Installation and Operation Manual Jul.05.07
Electric Shock - Rescue Methods
Electricity can damage the body in a number of ways. It may interfere with the proper functioning
of the nervous system and the heart action, it can subject the body to extreme heat and can
cause severe muscular contractions. The path that the current of electricity takes through the
body is important. Currents that pass from hand to hand or from hand to foot may pass directly
through the heart and upset its normal functioning. This threat to life is related to the amount of
current or amperage that will flow through a victim's body. Very little current (as little as 10 mA)
can result in severe shock or death.
Speed in the application of first aid measures is absolutely essential in cases of electrical injury.
As soon as the victim is freed safely from the source of the electrical current, if breathing has
stopped, artificial respiration should be commenced immediately. If the carotid pulse cannot be
felt, external cardiac massage should be commenced simultaneously. Resuscitation should be
continued until the patient is breathing on his own or until medical aid arrives. Survival rates can
be quite high if cardiopulmonary resuscitation is started within 3 to 4 minutes of the injury being
received.
Act At Once - Delay or Indecision May Be Fatal
1. Turn OFF the electrical source.
2. Commence artificial respiration immediately.
3. Treat for burns, bleeding and shock.
Removing a Casualty From Electrical Contact
LOW VOLTAGE - 0 to 240 volts (household use)
Switch off the current, if possible and time permits. If the switch cannot be located immediately
and the supply is through a flexible cord or cable, the current may be shut off by removing the
plug or even breaking the cable or wrenching free. Never attempt to shut off current by cutting
cord with a knife or scissors.
If the current cannot be shut off, the greatest care is necessary in removing the casualty.
Household rubber gloves, rubber or plastic hose (if there is no water in them), a dry unpainted
stick, or a clean dry rope can be used to free victim.
HIGH VOLTAGE - 240 volts and up (industrial machines and power lines)
Do not touch any person or equipment in contact with a wire.
Use a dry, unpainted pole, clean dry rope, dry rubber, or plastic water hose to separate the
casualty from the contact.
Keep as far away as possible.
Do not touch the casualty until the casualty is free.

Toxic Hazard Warning
There are devices used in this equipment containing beryllium oxide ceramic, which is non-
hazardous during normal device operation and under normal device failure conditions. These
devices are specifically identified in the equipment manual’s parts list(s).
DO NOT cut, crush or grind devices because the resulting dust may be HAZARDOUS IF
INHALED. Unserviceable devices should be disposed of as harmful waste.
