32 Tempest®24 00 2 -Channel Wireless Intercom System
Selecti ng a Frequency Band
The Tempest 2.4GHz wireless system is approved for license free use in most countries. However, due to diff erences in
radio spectrum regulati ons, some countries require that 2.4GHz equipment limit or adjust its RF spectrum operati on.
Always determine if there are country specifi c frequency restricti ons that apply and select the required frequency
band as described below. Tempest performs RF frequency adjustment automati cally when you select the appropriate
frequency band from the “Tech Menu.” Note: This is a legal requirement in some countries.
It is only necessary to use this feature if you use Tempest in one of the countries with special frequency requirements.
Otherwise, Band 1 is the default and should be used for maximum RF performance.
If the Tempest Wireless system is transported to a country with special requirements, navigate to the Radio
Confi gurati on screen in the “Tech Menu” to select the appropriate frequency band from the “Set Band” menu screen
in the BaseStati on.
Aft er changing the frequency band selecti on it is necessary to “pair” each BeltStati on with the BaseStati on so the
informati on can be transmitt ed from the BaseStati on to the BeltStati on.
See the “Pairing with BeltStati ons” secti on of this manual for more informati on on pairing.
