Messages Messages requiring alerts alternate with the standby frequency field. The following messages may be displayed: STUCK PTT !!! This displays when transmission has been active for 35 seconds. The V16 conforms to the requirements of DO-207. After 35 seconds the V16 reverts back to receive mode even if the PTT remains active. - Page 10 For new installations, please ensure that your antenna has a properly configured ground plane of sufficient size.

Page 13: Entering A New Standby Frequency
Entering a new standby frequency Using the numeric keypad Touch the standby frequency to activate the numeric keypad. Entry starts with the 10's of MHZ (you do not need to type the 100's of MHZ). A blinking cursor shows the digit you are changing. Only valid numerics for a given position may be entered. For example, the 10's of MHZ will only accept the numbers "1", "2"... - Page 14 When satisfied with your selection and you would like to change the Khz, "Click" the knob. Change the 100's of KHZ by rotating the knob. When satisfied, "Click" the knob. Now change the 10's and 1's of the Khz portion by rotating the knob. "Click" when done - you return to the normal display with the new standby frequency.

Frequency lists downloaded from external devices COM lists If at least one frequency list downloaded from an external source is available then your channel selection button is bracketed <CH>. Tapping the CH button will bring up a list selection display: Each external list is identified by an airport ID (as downloaded from the external device). -
Page 17: Nav Lists
NAV lists If your Razor is selected as a NAV head then you will be given the choice of either a VOR or ILS (or both) list – provided either of these has been downloaded from an external device. After you choose a frequency from either list or the internal list you will be asked if you would like to select that frequency to the primary or secondary NAV frequency. - Page 18 Page 18...

Similar, tapping the NAV section of the display changes the display to NAV mode. This allows you control the NAV device. If no activity is detected for 6 seconds the Razor reverts back to the NAVCOM display. While the NAVCOM display is showing the rotary control can be used to adjust the OBS bearing if the primary NAV frequency is tuned to a VOR station. -

control. The control in this case is speed sensitive – if you turn faster the OBS will change in bigger steps allowing you to set the desired radial very quickly. The “TO/FROM” flag indicator will change automatically based on the current received radial and the selected OBS. -
Page 23: Adjusting The Squelch
Back course selection is indicated on the ILS needles display using 4 sets of “BC” indicators. Ensure you are familiar with localizer operation and back course navigation before using the ILS facilites in the Razor. Enabled back course will reverse the localizer needle as you are approaching the localizer “from behind”. -
Page 24: The Audio Output
When a morse signal is detected the N16 attempts to decode it and sends the result to the Razor head. Up to 4 letters may be contained. These letters will be shown either next to the VOR label or LOC label marked by square brackets. If no code has been detected [----] is shown. -
Page 25: Channel Identification By Text
The Razor will first search any downloaded lists for a match before searching its own channel storage. The Razor will search only appropriate lists – for example it will not search VOR or ILS lists if the Razor is set to COM mode. -
Page 26: The Menu
All of the COM setup items and the text displayed originates from the connected V16 transceiver. Please refer to the V16 transceiver manual for information on the available setups. The "Head" setup groups all of the setup actions you can perform on the Razor head itself, including editing the channel list. Page 26... -
Page 27: Com Setup Menu
Note: items presented here for setup and the text shown is determined by the V16 transceiver, not the head. If you, for example, update the firmware of the V16 and this update changes or adds to the setup functions, then the Razor will reflect these changes without needing an update itself. -

NAVCOM mode is selected). This means, regardless of your selection of the Razor mode as COM or NAV the protocol is not affected. This means for example, even if your Razor is selected as COM only – your RS232 port behaves as NAVCOM if a NAVCOM emulation has been selected. -
Page 30: Rotary Rollover/Clamp
Razor head firmware The firmware in your Razor head can be updated by means of a RS232 connection to a PC. You require the new firmware (download from MGL Avionics website) which comes in the form of an application (exe file) that can execute on a Windows PC. -
Page 31: Editing Channel Memory
You may enter both COM as well as NAV frequencies. Should you choose from the channel list in operation, you will be presented with either COM or NAV frequencies depending on the current mode the Razor is operating in. You may use up to 100 channels. -

Page 36: Typical Connection Diagrams
This diagram shows the connection of one or two heads to a V16 transceiver. Note that audio, PTT and other transceiver related wiring is not shown for clarity. At minimum you only need 4 wires to connect to a Razor head – power supply, ground and the two CAN bus wires. -

Page 42: Garmin Protocol Limitations
Garmin protocol limitations As part of the setup you can select your Razor to emulate various Garmin protocols used for both COM and NAVCOM systems. The protocols are generally fully implemented but there are some differences. For example there are some protocol items that are related specifically to Garmin systems such as diagnostics information mostly intended for workshops or firmware version information. -

Page 45: Using Audio Transformer On The Aux Input
Using audio transformer on the AUX input Depending on your desired audio source it may be advisable to electrically isolate the source from the V16 (or N16). This could be due to the need to prevent ground loops or if the source is at a different electrical potential.
