Introduction Congratulations on buying an Altimaster Neptune! Neptune information is constantly being updated. Please refer to our website, www.alti-2.com, for the latest information. All altitude measurements are referred to in feet in this manual. Software Upgrades The Neptune has an Infrared interface which allows you to update the built-in software as new versions become available.
Basic Operation All menus have the same basic operation; the top and bottom buttons move the cursor and the center button selects the highlighted choice. Basic Setup Procedure Insert Battery Remove the two screws securing the battery cover using a Phillips screwdriver. Be careful not to lose the O ring.

Insert one type Duracell DL2450 (or equivalent) battery. 2 batteries are provided; 1 is a spare. The battery should only be inserted with the “+” side up, i.e. toward the buttons. Do not let metal of any kind to come in contact with the battery, and do not allow two batteries to touch each other.
Fitting the Helmet Clip If you wish to use Neptune as an external audible altimeter, use the helmet clip and tie wraps provided. Align the Neptune’s speaker with the speaker hole in the helmet clip. Failure to do so may result in inaudible alarms.
Hand Mount If you wish to use Neptune as a visual altimeter we suggest you use the hand mount provided. Lay the hand mount across the back of the Neptune. Line up the four (4) holes with the threaded inserts in the back of the Neptune and insert the screws provided, with the washers between the fabric and the screws.
Time and Date Setting the time and date is typical of many Neptune setup menus. This adjustment is explained in detail to familiarize you with the menu system. The system starts up in the ground screen. It displays time, date and temperature. Icons indicate: •...
The cursor will already be on the “Hours” setting. Use the top and bottom buttons to increase or decrease the number, then press “Select” and the cursor will move to the next item. When all entries have been adjusted the system will automatically exit from this screen.
• Neptune software to be updated • The log book to be downloaded to Paralog. For Neptune software updates, go to www.alti-2.com. Full download instructions are included with the program software. Instructions on downloading jumps to Paralog can be found in the Log Book section of this manual.
Display Screens / Modes Ground The ground display shows time, date and temperature, and also shows status icons for backlight, logbook, alarms, and battery. The Neptune has a power saving mode which switches the display off after 30 minutes. The Neptune will continue to function as normal; the display can be reactivated by pushing any button.
Altitude When “Alt” is showed in the bottom right of the screen (in Ground Mode and Climb Mode), push the bottom button to go to the “Altitude” screen. This shows altitude AGL (above ground level) and altitude MSL (Mean Sea Level). THE MSL value is actually QNE, or Pressure Altitude, which means that the value will change with barometric pressure.
• Current altitude • Climb Rate • Temperature • Status icons In the screen above, the backlight, logbook, & freefall alarms are enabled, and the battery is full. Canopy alarms are disabled. In Climb Mode, you can adjust any setting, look at your logbook, and turn functions on and off, right up until you exit the plane.
NOTE: If the analog bar (fun meter” is empty it does NOT mean you are at 3,000 feet, it means you are BELOW 3,000’ – check the numbers!! Canopy The canopy display shows altitude in feet to a resolution of 10 feet. It also shows rate of descent in feet per second.

In the Ground screen, the underlined alarm icon indicates that freefall and canopy alarms are both activated. We recommend that alarms are disabled (Menu > System > Options 1 > Audible > Disable) if you are using Neptune as a visual altimeter.
To exit without making changes select “OK” or to change the setting select “Edit/Select”. Freefall Alarms The following procedure shows how to edit and select another freefall alarm group: When you select “Edit/Select,” you will see the screen shown on the left. Group 1 in this case is the active group.

Scroll through the list to change the group name. In this case “4-way” has been selected. Press “Select” to confirm the new name. The same method is used to select and change the 3 alarm altitudes. When the alarm name and altitudes are correct, highlight “Activate Group,”...
way, 8-way, or 4-way. This group name will be written to the log of that particular jump, whether alarms are enabled or not. Freefall alarms will sound only if freefall speeds are reached at the preset altitudes. If, for example, your Group 1 alarms are set at 4500’, 3000’, and 1500’, the third alarm will only go off if you are still in freefall at 1500’.
Page 19
Default settings are 1500’, 1000’ and 600’. Change swoop alarm altitudes as you would change freefall alarms. Select the item you wish to change. The top button will increase the altitude in increments of 10’; the bottom button will decrease. Once you have set your alarm altitudes, select “Activate Grp”...
The two sets of double arrows indicate that freefall group “4-way” and canopy group “Swoop 1” are both enabled. The Ground screen alarm icon will also be underlined. To turn off canopy alarms, select that group. Select “GRP ACTIVE”. The option to activate this alarm group will be displayed.
Page 21
A summary of your jumps is available (Menu > Log Book > Summary), which shows total jumps and total freefall time. Detailed jump logs can be viewed for the last 10 jumps, and can be reviewed on a jump by jump basis (Menu > Log Book > View Logs). You will see the latest jump number displayed.
Page 22
When you select “Next” you will see: • Avg: Average velocity for the freefall portion of your skydive, where freefall = exit altitude until you are under a fully open canopy • 12K: Average velocity between 12,500’ and 11,500’ • 9K: Average velocity between 9,500’...

If you descend with the aircraft, the Neptune may log a jump. Use “Delete Last” (Menu > Log Book > Delete Last) to erase the jump. If you encounter any logging errors, please make sure that you have the latest version of software.
After connecting with Paralog, your jumps will be downloaded into that program. DZ Setup The “Set DZ Offset” (Menu > DZ Setup > Set DZ Offset) function allows you to take off at one location and land at another DZ which is at a different altitude. The only function of DZ offset is to enter a number which is either added or subtracted from the AGL altitude that is displayed.
To cancel manual mode: Menu > DZ Setup > Manual Mode > Cancel Manual > Disable If the altitude on the ground is not zero AGL, go to Menu > DZ Setup > IM on DZ. This function is useful if, for example, you drive up a hill and then get in the aircraft a short time later.
The menu sequence to enable the backlight is Menu > System > Options 1 > Backlight > Enable. The backlight icon will appear on the ground screen to confirm that it is activated. When enabled, the backlight will stay on for 3 seconds every time you press a button, and will stay on when freefall and/or canopy flight is detected.
Training Mode To access Training Mode, go to Menu > System > Modes > Setup Training. Edit the desired exit and deployment altitudes in the same way alarm altitudes are set, and then select “Exit”. To enter Training Mode, select “Training”. There are three options: “High Speed Mal”, “Low Speed Mal”...
Disassembly The Neptune cannot be disassembled by the user. Unless specifically described here, all maintenance on your altimeter should be performed by Alti-2, Inc., 1400 Flightline Blvd. Suite E, Deland, FL 32724 Tel: (386) 943 9333 Fax: (386) 943 9303 e-mail: info@alti-2.com General Cleaning Wipe altimeter with a damp cloth.
Maintenance after submersion in salt water CAUTION Salt deposits must be removed from the filter after submersion in salt water. Failure to remove salt deposits may lead to the filter becoming blocked and serious lag may occur in freefall as a result. To remove salt deposits submerge the altimeter in clean fresh water for approximately 10 minutes.
Please be sure to include contact information such as Phone Number, Fax Number, and/or email address, and a description of the problem. Status on your altimeter can be checked by contacting the Alti-2, Inc. Service Department, or by initiating a Request for Repair Status through the Alti-2, Inc.
