Open the circuit by switching off the line switches. If that is not possible protect yourself with dry material and free the patient from the conductor. 2.1.1 Artificial respiration It is important to start mouth resuscitation at once and to call a doctor immediately. Suggested procedure for mouth to mouth resuscitation method is described in Table 1. 2.1.2 Treatment of burns This treatment should be used after the patient has regained consciousness. It can also be employed while artificial respiration is being applied (in this case there should be at least two persons present). Warning • Do not attempt to remove clothing from burnt sections • Apply dry gauze on the burns • Do not apply ointments or other oily substances.

Cabinets must provide adequate ventilation and must meet the following criteria:  45.0 cm (17.71 inches) deep  48.3 cm (19 inches) wide  13.4 x 3 cm (15.75 inches) high  Two mounting rails 5 cm (2 inches) from front cabinet with front mounting holes 5.7 cm (2.25 inches) apart (center to center). The front of the device is provided with four holes for M6 screws (highlighted above in green) for each level. This permits to fasten the device to a 19” rack by means of 4 M6 screws for each level. If several devices are installed in a single cabinet, be sure equipment have to be spaced at least by 1/2 RU (2,2 cm, 0,8 inches).to allow for adequate cooling. Cabinets must have a least 15 cm (6 inches) of open space between the air vents and any wall or other cabinets. This allows adequate air flow. When multiple cabinets (each equipped with several repeaters) are installed in an enclosed area, ensure appropriate ventilation and consider air conditioning or other climate control equipment to satisfy the temperature requirements.

Thanks to a microprocessor mounted on board, the module is able to implement the PUFF technology (Powerful Universal Forming Function) for the shaping of transient power in order to obtain compliance with the rapid transient rules of ACP (Adjacent Channel Power). The microprocessor also manages completely the operation of the module: this would remove any calibration procedures. All configuration changes are performed via software. Other main functionalities are:  continuous transmitter’s operations (100% duty cycle).  Output power selectable between two values (Phi and Plo), each of which can be SW set to a nominal value between 10 and 110 Watts.  final stage protected against excessive mismatching output power. In the case that VSWR remains above a set threshold (eg ReturnLoss = 5dB) for more than a fixed time, the module is able to send an alert and the output power will not exceed a safety value (eg ≤ 10watt).  temperature threshold alarm: if the temperature remains above a set value for more than a fixed time, the module is able to send an alert and will ensure that the RF output power will not exceed a predetermined safe value. The front panel is provided with bi-color leds to help in troubleshooting the system. The table below describes the meaning of the leds: LED Color Label Description 1 Green PWR High High Power level selected and correctly On Air Red PWR fail Emitted power less than a FW configured threshold (3 dB typical) 2 Green PWR low Low Power level selected and correctly On Air Red VSWR On Air and VSWR level is greater than FW configured threshold 3 Green Control bus busy Activity on the control bus
