1. Wearing The Radio

1. The radio comes with a clip to attach to your belt or apron.  Radios fall out of pockets.
2. Place the headband on your head.  Be careful.  Some headbands are plastic and break easily.
3. Adjust the headband for a comfortable fit.
4. Clip the antenna to the headband (It is safer and doesn’t need to be deployed).
5. Make sure you can easily and comfortably reach the grey “PUSH TO TALK” button. 

2. Setting Up The Radio To Transmit

1. Move the power switch to "MAN".  The red light will momentarily flash.
2. DO NOT use the "VOX" setting! This automatically transmits as soon as you speak
3. The “VOX/MIC” switch is not used in our operation.
4. Turn the channel selector to the channel the club is using that day.  This is announced during the morning briefing.  Ask someone if you don't know (Usually channel "D") 
5. Move the "VOLUME" switch to a comfortable listening level. ("VOLUME" has no effect on transmit level.  The transmit volume is preset within the radio.
6. Adjust the microphone so that it is level with your mouth and a little to one side so that you aren't blowing into it.  The transmit volume is affected by the position of the microphone.  If it is pointed away from you, the transmit volume will be reduced.

3. Transmitting

1. Listen before transmitting to ensure that you minimize interference with other people.
2. Think what you are going to say before pressing the “PUSH TO TALK” button. 
3. To transmit, press and hold the "PUSH TO TALK" button.
4. Only one person should transmit at a time.  IF you press the "PUSH TO TALK" button while someone else is talking, transmissions will be garbled.  This is known as "doubling" . Wait until you hear a gap in transmissions before pressing your "PUSH TO TALK" button.

4. Low Battery 

1.Your transmissions may become distorted and break up.  It’s time to replace the battery. 
2. Move the power switch to  "OFF". 
3. Remove the cover on the back.  Pull out the 9 volt battery.  CAREFULLY remove the battery from its clip and replace it. Broken battery clips are our number one radio problem.

5. When You Are Finished With The Radio

1. Turn the power switch to “OFF”.
2. return it to the table where you got it.
3. Do not remove the battery

6. Problems With Radios - Report Them!

1. Radio problems may not be due to a radio fault.
2. Is the battery light ON?  The battery is low and needs to be changed.
3. Are you on the correct channel?  Check with another engineer.
4. On “MAN” mode?  (Do not use “VOX”) 
5. Test the radio.  Do not test a radio on the active channel.  Go to a different channel and get someone to conduct a test with you there so that you don't interfere with normal operations.

6. Refer your problem radio to Pat Brewer or Mike Vincent. 
7. Fill out a “bad order” tag and attach it to the radio. On the tag write down the serial number of the radio (on its back), the nature of the problem, the date, and your name. 

8. Pick up another radio (after you have faulted the problem radio).

7. Packing The Radios

1. Turn the power switch to “OFF” on all radios.
2. Do not remove the batteries. 
3. Coil the headset cord loosely and place the radio in a pouch.
The headsets shall be put away in their pouch after each operating day.

5  Pouches are packed in two layers to distribute weight and prevent damage
6. Put 12 radios in the lower level with pouch open side up.
7. Put the remaining radios in the cardboard tray and on top of the first layer.
