The Mounting and Use of Radios
SAMPSON RACING PRODUCTS
- Radios that have rechargeable batteries need to be fully charged before each use and completely discharged before recharging to prolong the life of the battery.
- Protect your radios from the elements. It is recommended they be placed inside of, or covered with, some sort of plastic bag.
- Mount the radio as high as possible and in an open area, making sure the antenna is not next to any metal components. Near an open window is best. If you use a remote antenna, do not coil the extra cable; make sure you have a clean ground surface.
- Mount the radio with vibration dampening material i.e. roll bar padding. Zip-tie the radio to the roll bar with padding between the bar and the radio.
- Again, make sure you mount the radio away from the elements.
The PTT Switch
- Mount the PTT to the steering wheel with the Velcro strap, route the coil cord along the steering column and zip-tie. Make sure there is enough slack or play in the cable so the wheel can be turned from the Left to Right Stops, without pulling the cord. If you use a removable steering wheel, leave enough slack so the wheel can be removed and stored without pulling the cord.
- Make sure that all connection points can be made without stressing the connection.
- Place and zip-tie the harness in appropriate locations to prevent movement and stress to the cable and connections.
- Protect the harness from being pinched, crimped or exposed to any chemicals.
- Placing the crew member away from obstructions and up high, i.e. on top of a motorhome or high in the stands etc., will ensure full coverage.
- Be careful not to drop the radio and again, make sure to keep the radio out of the elements.
We supply you with “P” Clamps, flat washers and rivets for your convenience BUT you can mount a helmet kit without putting any holes in your helmet w/ a little patience and good contact cement or a hot glue gun.
Tools Required: Drill w/ 1/8 drill bit, pop-rivet gun, glue of some sort, clamps, 1” puddy knife and patience!
1. Put on your helmet and note the area in front of your mouth, this is where you will position the mic. Take off the helmet.
- Next determine which side of the helmet you want the wires to run depending on where you mount the harness in your car.
- Work loose the cheek pad on the side you have chosen (Fig. 1), place the boom w/ mic through the cheek pad and run the “Y” block back towards the helmet chin strap to the point where the webbing attaches to the helmet, Zip-Tie the “Y” block.
- Pull the 3.5mm earbud jack down and let it hang out the bottom of your helmet. Make sure to leave enough length to grasp it.
- Run the harness plug toward the rear of your helmet and if needed, use the “P” clamp and rivet supplied to attach it. Make sure this point of attachment is SECURE. Over time, this attachment point will suffer the most wear and tear. Use the flat washer on the “P” clamp side, to avoid pulling it through. (Fig. 2)
- Now fit the cheek pad back into place and use contact cement or hot glue to secure.
Remember when plugging in and unplugging ALWAYS use care and hold both halves of the connector, DO NOT just pull on one side.
