Rate adjustment by inhibition. The rate can only be
measured using an instrument capable of measuring for
sixty seconds or multiple times sixty seconds.
1.1 Fitting the battery
Slide the battery under the battery clamp no. 4400. Gently
press on battery to position it in place with the bridle +
no. 4401.
