Type-1 phaser settings (or levels) are 1-8. Type-2 phasers have an additional eight settings [TNG: Frame of Mind], so they have settings 1-16. In [DS9: Return To Grace] that is confirmed for the standard Type-3 phaser rifle, and also that the phaser rifle as a fully autonomous recharge, and multiple target acquisition, and is gyrostabilised.
Encyclopaedia states: "A phaser rifle was used only once during the Original Series, the one wielded by Kirk in [TOS: Where No Man Has Gone Before]. Phaser rifles were not used for the first few seasons of [Star Trek: The Next Generation], until [TNG: The Mind's Eye], because it was believed that type-1 and type-2 phasers were powerful enough to handle just about anything."

| SETTING | DESIGNATION | EFFECT Description includes a standardised damage index is derived for setting comparisons: each whole number represents the number of centimetres of material that is penetrated or damaged molecularly. |
| Setting 1 | Light Stun |
Discharge energy index 15.75 for 0.25 seconds, SEM:NDF ratio not applicable. This setting is calibrated for base humanoid physiology, and causes temporary CNS impairment. Subjects remain unconscious for up to five minutes. Higher levels of reversible CNS damage resuit from repeated long exposures. The discharge energy index is related to RNE protonic charge levels. Standard median-density composite structural material samples are not permanently affected, although small vibrational warming will be detected. A standard composite sample consists of multiple layers of tritanium, duranium, cortenite, lignin, and lithium-silicon-carbon 372. The damage index for this setting is zero. |
| Setting 2 | Medium Stun |
Discharge energy 45.30 for 0.75 seconds, SEM:NDF ratio not applicable. Base-type
humanoids are rendered unconscious for up to fifteen minutes, resistant humanoids up to five minutes. Long exposures produce low levels of irreversible CNS and epithelial damage. Structural materials are not affected, though higher levels of vibrational warming are evident. The damage index is zero. |
| Setting 3 | Heavy Stun |
Dscharge energy 160.65 for 1.025 seconds, SEM:NDF ratio not applicable. Base humanoids remain in a sleep state for approximately one hour, resistant bioforms for fifteen minutes. Single discharges raise 1 cc of liquid water by 1OO°C. Structural samples experience significant levels of thermal radiation. The damage index is 1. |
| Setting 4 | Thermal Effects |
Discharge energy 515.75 for 1.5 seconds, SEM:NDF ratio not applicable. Base humanoids experience extensive CNS damage and epidermal EM trauma. Structural materials exhibit visible thermal shock. Discharges of longer than five seconds produce deep heat storage effects within metal alloys. The damage index is 3.5. |
| Setting 5 | Thermal Effects |
Discharge energy 857.5 for 1.5 seconds, SEM:NDF ratio 250:1. Humanoid tissue experiences severe burn effects but, due to water content, deep layers will not char. Simple personnel forcefields are penetrated after five seconds. Large away team fields will not be
affected. The damage index is 7. |
| Setting 6 | Disruption Effects |
Discharge energy 2,700 for 1.75 seconds, SEM:NDF ratio 90:1. Organic tissues and
structural materials exhibit comparable penetration and molecular damage effects as higher energies cause matter to dissociate rapidly. Familiar thermal effects begin decreasing
at this level. The damage index is 15. |
| Setting 7 | Disruption Effects |
Discharge energy 4,900 for 1.75 seconds, SEM:NDF ratio 1:1. Organic tissue damage
causes immediate cessation of life processes, since disruption effects become widespread. The damage index is 50. |
| Setting 8 | Disruption Effects |
Discharge energy 15,000 for 1.75 seconds, SEM:NDF ratio 1:3. Cascading disruption
forces cause humanoid organisms to vaporise, as 50% of affected matter transitions out of the continuum. The damage index is 120; all unprotected matter is affected and penetrated
according to depth/time. |
| Setting 9 | Disruption Effects |
Discharge energy 65,000 for 1.5 seconds, SEM:NDF ratio 1:7. The damage index is
300; medium alloy or ceramic structural materials over 100 cm thickness begin exhibiting energy rebound prior to vaporisation. |
| Setting 10 | Disruption Effects |
Discharge energy 1 25,000 for 1.3 seconds, SEM:NDF ratio 1:9. The damage index is 450; heavy alloy structural materials absorb or rebound energy, 0.55 sec delay before material vaporises. |
| Setting 11 | Explosive/Disruption Effects |
Discharge energy 300,000 for 0.78 seconds, SEM:NDF ratio 1:1 1. The damage index is 670; ultradense alloy structural materials absorb/rebound energy, 0.20 sec delayed reaction before material vaporises. Light geologic displacement; <1 0 M3 rock/ore of 6.0 g/cm3 explosively uncoupled per discharge. |
| Setting 12 | Explosive/Disruption Effects |
Discharge energy 540,000 for 0.82 seconds, SEM:NDF ratio 1:1 4. The damage index is 940; ultradense alloy structural materials absorb/rebound energy, 0.1 sec delayed reaction before material vaporises. Medium geologic displacement; <50 M3 rock/ore of 6.0 g/CM3 explosively uncoupled per discharge. |
| Setting 13 | Explosive/Disruption Effects |
Discharge energy 720,000 for 0.82 seconds, SEM:NDF ratio 1:1 8. The damage index is 1,1 00; shielded matter exhibits minor vibrational heating effects. Medium geologic displacement; <90 m3 rock/ore of 6.0 g/CM3 explosively uncoupled per discharge. |
| Setting 14 | Explosive/Disruption Effects |
Discharge energy 930,000 for 0.75 seconds, SEM:NDF ratio 1:20. The damage index is 1,430; shielded matter exhibits medium vibrational heating effects. Heavy geologic displacement; <1 60 M3 rock/ore of 6.0 g/CM3 explosively uncoupled per discharge. |
| Setting 15 | Explosive/Disruption Effects |
Discharge energy 1. 1 7 x 106 for 0.32 seconds, SEM:NDF ratio 1:25. The damage index is 1,850; shielded matter exhibits major vibrational heating effects. Heavy geologic displacement; <370 M3 rock/ore of 6.0 g/CM3 explosively uncoupled per discharge. |
| Setting 16 | Explosive/Disruption Effects |

damage index is 2,450; shielded matter exhibits light mechanical fracturing damage. Heavy geologic displacement; <650 M3 rock/ore of 6.0 g/CM3 explosively uncoupled per
discharge. |
