TELEX Wireless Intercom System and turned on any auxiliary equipment you are ready to test the overall performance by “Walking” the TELEX system through the areas in which you will be using it. Before you begin your walk-thru check the fol- lowing: TR-200 Battery Check. -
Page 37: Troubleshooting
Change the location of the base unit and antennas or avoid the bad areas with the remote beltpacks. Make sure Telex TR-200 beltpack is turned on - this will usually eliminate the interfer- ing signal. If not using a beltpack, make sure the corresponding enable switch at the base is disengaged. -
Page 38: Battery Information
BATTERY INFORMATION Improper battery selection, use, installation and care are the cause of numerous wireless system failures. Alkaline Batteries: Alkaline batteries such as Mallory’s DURACELL or Eveready’s ENER- GIZER provide the most reliable operation in wireless transceivers. The use of low cost car- bon-zinc batteries is NOT recommended. -
