CAUTION
Rate monitoring systems may be inaccurate. Over-exercising may result in serious injury or death. If you feel faint stop exercising immediately.
“Peak Power” is not suitable for use in applications where the health and safety of a patient may be dependent on the accuracy of those parameters.
Use of the exercise Target program requires medical supervision and compliance with exercise testing guidelines.

DISPLAY FEATURES
LINE 1 – RESISTANCE
The Resistance window displays the current resistance or OFF. Adjust the resistance using the (+/-) Thumb Buttons located on top of the Thigh Cushion. When the window displays OFF, the machine enters a low power consumption sleep mode to increase battery life. Normal operation may be resumed by pressing either the Thumb Button or by inserting the chip. If this window displays the low battery signal (“Lo-bA”), the batteries are getting weak and should be replaced soon (D batteries,quantity 2; refer to page 16 “Battery Replacement” for complete instructions).
LINE 2 – SET OR REPETITIONS
This window displays the current repetition count except immediately after an ship is first inserted, in which case it displays the current set. The set count may range from 1 to 9 and is signaled by the appearance of three horizontal bars in the left digit. The number of sets is defined as the number of sets of exercises performed in a four-hour period. Once four hours have passed, the machine assumes that the user is returning for a new visit. The repetition count may range from 0 to 99. The repetition count may be reset by momentarily pressing both increase and decrease (+/-)Thumb Buttons simultaneously. In Power Test mode, the window will display the repetition count per test section (refer to page 14 “Power Test” for complete instructions).
LINE 3- TARGET REPS
The Target Reps window displays the number of repetitions performed on the corresponding set of the previous visit, if that set was a normal workout set and an eChip is inserted. If the corresponding set of the previous visit was a Power Test, the display will show “Pr.” When in Power Test mode, the window will display “P1” during the low resistance test set and “P2” during the high resistance test set (refer to page 14 “Power Test” for complete instructions).
LINE 4 – CURRENT POWER / PERCENT OF PEAK POWER
The Current Power window can display 4 different values. During an exercise set, it displays the percent of peak power achieved for the most recent repetition. At the end of a Power Test, this window displays the resistance to use to achieve maximum power. When an eChip is inserted and the previous corresponding set was a normal workout set, it displays the resistance used for that set. When an eChip is inserted, and the previous corresponding set was a Power Test, it displays the resistance to use to achieve maximum power. When the calculated resistance to achieve maximum power is displayed, it flashes. In summary, during an exercise set, this window displays the power for the current rep, at the end of a Power Test it is the resistance to use for training at maximum power; when a chip is inserted it is the resistance to set into the window above before exercising.
LINE 5 – PEAK POWER
The Peak Power window displays the highest power that has occurred during this workout or since the data was the last reset.
LINE 6 – MACHINE ADJUSTMENT
When using the chip, Seat and Leg positions (including ROM settings, 1222 model only) can be tracked and recorded. Press the arrows located directly above/below each window to input settings.
SEAT: Fore/aft position of the Seat Back (16 position settings).
LEG: Position settings 1 – 8 of the Leg Cushion.
ROM (1222 model only): START settings 1 – 9, 0, or A (START ROM window located to the right of the LEG window). STOP settings 1 – 9, 0, A, C, or E (STOP ROM window located to the right of the START ROM window).
NOTE: The adjustments may only be changed immediately after the eChip is inserted and before the third repetition has occurred. Once three repetitions are performed, the machine adjustments cannot be changed until the eChip has been removed and reinserted. Machine adjustments apply to a machine and cannot be changed from set to set.
LINE 7 – eCHIP READER
The eChip Reader, located at the bottom right of the Power Display, receives and reads your eChip data.
LINE 8 – eCHIP
The eChip collects workout data and can store up to 24 separate equipment models (up to 4 equipment position settings per model) and up to 240 separate workout sets across Keiser Air and Infinity Series. Designed as an electronic replacement for the hand-written exercise card, the eChip enables recall and set-up of the exercise equipment upon the next workout. The Keiser eChip software allows saved eChip data to be viewed, stored, and exported (.csv file format) for analysis.
NOTE: Three user eChips (red color) come standard with your Air250 Seated Leg Curl. The Keiser USB Power Kit (a USB adapter to transfer data from your eChip to your computer and Time Set eChips to set the time zone/time on your Air250 Seated Leg Curl) is available. For parts orders, contact Keiser Customer Support (see back cover for contact information).
Keiser eChip software system requirements, download, and user manual are available at keiser.com/support (search: eChip).
