• RF input power feed:
– In the TV band for preamplifier:
OFF, +5, +12, +15, +18, +24 V (0.3 A)
– In the SAT band for LNB: OFF, +13 V, +18V, 22 KHz (0.3 A)
• DiSEqC: 4, 8, 12 or 16 polarizations, DiSEqC "a.b.c.d" already pre–programmed in sequence and very easy to use. It can power any
type of LNB (analog or DiSEqC, single or dual feed) and any type of multiswitch (analog or DiSEqC with 5, 9, 13, 17 cables)
• RF IN automatic preamplifier: this is automatically inserted when the RF input level is less than the set thresholds, it is
automatically calculated from the measurement and the activation is shown by the relative LED on the front panel near the RF input
• Power supply:
– Built–in rechargeable batteries: 12 V x 7 A (LEAD GEL)
– Voltage load: 17/20 Vac or 20/24 Vdc (1.1 A), (connector: Ø 5,5 x 2,2)
– AC/AC adapter: 230 Vac (117V opt.),
output: 17 Vac (supplied)
• LNB current or Preampl meas.: 1 to 300 mA
• Buzzer: level or quality parameter selection
• Battery duration at 25°C: 5 hours in TV AN at 20°, 4 hours in digital SAT depending on LNB consumption.
• low battery indicator: with acoustic signalling and shown on TFT and auto turn–off from micro-controller

• Picture display:
5.5" TFT color for DM-14C, CRT 5.5” B/W for DM-14B PAL (encased and antishock)
(encased and anti-shock). Please note that for 5,5” TFT monitors if Pixel are turned off the tollerance, according to the manufacturer, is 1
pixel in the centre and 2 pixels around the perimeter.
• Auto–off timer: after 5 mins without use (select-able on/off, always starts up from last fuction)
• Auto–test menu: Self–test of main internal digital circuits
• RF input overload protection: electronic up to 60 Vac, or total with manual side safety switch
• DC AT RF IN (LNB) current measurement: 0–300 mA accuracy, 3 mA typ. (5 max)
• TXT (teletext) selection and visualization
• Measurement voltmeter: AC 110 V max, DC +110 V max applied to RF input
• Video test generator: to check CRT linearity and for modular an CCT network tests. Available at scart socket, on pin 19
• File manager: to maintain internal data files (canalizations, memory plans, saved spectrums), data logger, etc.
• Defrag function: for memories defrag
