• To store your Platinum 900 battery pac for long periods, do the following: Charge the batteries for a full 10 hours and store at room temperature away from extreme humidity. They can be stored for several months in this condition. Charge for a full 10 hours before your next use. The batteries are rated for at least 500 charging cycles.

• We have found that by drilling two holes in the back of the Platinum 900 speakers, it eliminates some of the unwanted frequencies and makes the voice reception a lot clearer. This simple "porting" really helps to get a crisp, clear voice through your speakers. As of May 4, 2003 all Platinum 900 have this done to their speakers and it is recommended that you do the same to yours if purchased before this date.
  

  Drilling Instructions:

  
  
• 1. Obtain a drill and a 3/16" drill bit.
• 2. Locate the space between the last T in COLLETT and the E in ELECTRONICS on the back of the speakers. This will be your first hole. (see fig. 1 for locations)
• 3. Gently drill through the plastic being careful not to go too far or go into the actual speaker itself. There is a metal support around the speaker that will stop the drill from going too far, but use caution and a gentle pressure just to be safe.
• 4. Locate the space between the S in ELECTRONICS and the L in LTD. This will be the place for your last hole.
• 5. Repeat step 3 for the last hole.
• 6. Repeat steps 1 to 5 for other speaker.
• 7. Re-install speakers into your helmet.

• Speaker Placement is very important to get the best results from your Platinum 900. We have found in testing that speakers even an inch away from optimal positioning will result in a very low volume, and hard to understand communication. The speakers must be directly across from your ear canal and only about 1/4 of an inch away. If the volume on your Platinum 900 is turned up more than half way you should reposition your speakers.

• Microphone Positioning is also very important because the microphone is specifically designed to work in one position. It must be positioned horizontally in front of your lips. (Like a harmonica) This is designed to eliminate exess backround noise and channel your voice to the microphone.

• All of the connections on your Platinum 900 are designed to be watertight and vibration proof. All connections should be made with the cords and the radio at room temperature. The speaker jack is considerably tight and some force may be needed, to seal the connection. You must push and twist the cord until it recesses into the radio about 1/4 of an inch. The same procedure applies to all other audio connections. The cords will then set into the radio. This will insure a watertight fit and they will not come out in extreme riding conditions.(see fig. below)
