2. Battery handle and accessories 2.1. Purpose The RIESTER battery handles described are used for supplying the instrument heads with power (the lamps are inclu-ded in appropriate instrument heads), also serving as a bracket 2.2. Battery handle range Important information Any instrument heads described in these operating instructions will fit the following battery handles and may therefore be individually combined. a) Type C battery handle incl. a 2.5 V order to operate these battery handles, you will require two commercial type C alkaline baby batteries (IEC standard designation LR14) or one 2.5 V rechargeable battery (Ri-Accu). The handle and the RIESTER rechargeable battery (ri-accu®) may only be charged by a RIESTER ri-charger® charging base. b) Type C battery handle incl. a 3.5 V This battery handle may only be operated with a RIESTER rechageable battery of 3.5 V (ri-accu®). This may only be charged in a RIESTER ri-charger® charging base. c) Type c rechargeable battery handle of 2.5 V or 3.5 V with a rheostat for charging in a mains socket of 230 V or 120 V This handle is available both as a 2.5 V or 3.5 V version and may be ordered for 230 V or 120 V mains operation. The handle is supplied with a suitable rechargeable battery (ri-accu®). Please note that the handle must be operated with a RIESTER rechargeable battery (ri-accu®)

2.3. Insertion and removal of batteries Handle types (2.2. a and b) Turn handle cover on bottom handle section. Depending on what handle has been purchased for what mains voltage (see 2.2), either insert 2 commercial alkaline type ”C” baby batteries of 1.5 V (IEC standard designation LR 14) or a RIESTER rechargeable battery (ri-accu®) of 2.5 or 3.5 V into the sleeve of the handle, with the plus pole pointing towards the top section of the handle. There is an additional arrow on the rechargeable battery next to the plus sign, indicating the direction for insertion into the handle. Retighten handle cover firmly over the handle. Remove batteries by first releasing the battery handle cover, followed by shaking the handle lightly. Prior to operation, insert rechargeable batteries (ri-accu®) into handle and charge with a RIESTER ri-charger® charging base. Each charging base is supplied with separate operating instructions which should be complied with. Handle types (2.2. c)) Prior to first start-up of the mains socket handle, charge for 24 hours in a mains socket. Attention: The plug-in handle should not be charged for longer than 24 houers. Leave rechargeable battery (ri-accu®) in the handle as supplied. Rotate bottom handle section in counter-clockwise direction to release, thus exposing the socket contacts. Round contacts are used for 220 V mains operation, flat contacts for 110 V. Now insert bottom handle section into socket for charging. Warning: Never leave handle in socket whilst the battery is replaced! When changing the rechargeable battery (ri-accu®), rotate battery handle cover at handle bottom section in counter-clockwise direction to release. Remove rechargeable battery (ri-accu®) from battery handle by shaking the handle lightly downwards. Insert rechargeable battery (ri-accu®) into battery handle. Ensure that rechargeable batteries of 2.5 V are inserted into the handle with the polished metal head first. For 3.5 V rechargeable batteries, the direction of insertion is unimportant. Firmly tighten battery handle cover in clockwise direction on handle. Mains voltage: Optionally 230 or 120 V Note: • When the unit is not being used for an extended period of time or when travelling, remove batteries from battery compartment. • Insert new batteries when the light intensity of the instrument is reduced, thus possibly affecting examination. • For maximum light it is recommended to insert two new high-quality batteries (as described in 2.2). • Should you suspect that fluid or condensation has penetrated into the handle, do not recharge. This may cause lethal electrocution, in particular in handles connected to a mains socket. Disposal Please note that batteries must be disposed of separately. For information ask your local council and/or environmental officer. 2.4. Attaching instrument heads Ensure that the knurled screw on the battery handle is released so far that the tip of the screw can no longer be seen in the interior of the support. Attach required instrument head to the support on the battery handle, 12
ensuring that the notch is directed towards the knurled screw. Fix by the locking screw. 2.5. Switching the instrument on/off Switch instrument on by pressing the red On/Off switch on the black knurled plastic ring (rheostat) and turning it to the left, away from the ”0”, whilst still keeping it pressed. Switch instrument off by keeping the On/Off switch pressed and turning it to the right to position ”0”. 2.6. Rheostat for control of light intensity The rheostat allows to set light intensity. Depending on how far the switch including the black knurled ring is being screwed in in counterclockwise or clockwise direction, light intensity will be increased or decreased. For orientation, use marking below the rheostat. 2.7. Spares Item No. 10426 Top handle section comprising a rheostat and plug-in locking system
