The models listed above have been modified to allow the Blue Call button (NHR-7A-CB) to activate the highest
priority call on the NHX Nurse Call System. When the Blue switch is pushed down to the lower position, the master
station will indicate the call with a fast intermittent call tone and flashing LED. The call can be cancelled only by
raising the switch to the upper position. All other call levels remain the same.
