| r6153. LE. From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.8/MA.18.10.34. Re Fitting of Wireless Sets. Replying to your LE8/C/16.10.34., we agree that with a number of wireless sets there is this possibility of the battery being run down due to the set being left on inadvertently. We do not however wish to add to the number of warning lamps on our chassis dashboard, but consider it more advisable for the wireless set makers to carry out your suggestion.
